What is the GUD Simulation League?

The Gridiron Uniform Database Simulation League (GSL) is a virtual football league.
Each team is owned by a single individual, who is in charge of the team logos, wordmarks, uniform design, and field design.
Each team is randomly assigned an offensive and defensive strength, which is used to simulate game outcomes.
Games are simulated automatically on the date of the game, and scores are posted 3 hours after the scheduled game time (all game times are US Eastern time).


How can I join the GSL?

If you are interested in becoming an owner of a GSL franchise, please contact us at gridironuniforms@gmail.com, giving your name as the franchise owner, a city to base your team, and a team name, to be given primary approval.
Team's must be based in major metropolitan areas of the US or Canada, and must be based in a stadium with a minimum capacity of 20,000 (think stadiums that would host teams in an XFL sized league).
Once you have given your intent to own a GSL franchise, you must provide team logos, wordmarks, uniforms, and a field design (or designs), to be given secondary approval.
You can send us logos, uniforms, and fields on any template you like, as long as they are .png files.
All uniform and field images will be converted to the standard GUD templates after approval.
The GUD can provide the field template image, but we are not making the full resolution uniform template available to the public.
You can request that the GUD members design your team's uniforms and field, if you'd like, or, you can choose to own one of the existing GUD created teams, shown in the 2020 GSL season.

After secondary approval, there is a final step for admission into the league.
Becoming an owner in the GSL requires a donation to the Gridiron Uniform Database of $20, for each calendar year there is a GSL season.
This donation is not to be sent until secondary approval into the league, and is the last step for admission into the GSL.
Why does a GSL franchise require a donation? Frankly, we need it to keep the site running.
As the site has become more popular, it has become more expensive to host.
All donations are strictly used for paying our hosting fees, and domain fees, as we at the GUD strongly commit to keeping the site not for profit.
The donation amount of owning a GSL franchise may fluctuate from year to year (but never more than $20), depending on our financial situation.
We hope that you, as fans of the GUD, can understand why owning a GSL franchise requires a donation, and we hope the GSL can provide a good return for franchise owners.


Cities and team names taken for 2021 season

The following cities and team names have been claimed for the upcoming 2021 season:

Atlanta Flying Fleet - Rob Holecko
Baltimore Bluebirds - Casey P. Snelick
Las Vegas Outlaws - Austin Snelick
Louisiana Royals - William Smythe
Louisville Lightning - Damon Richmond II
Memphis Comets - Jayson Jones
Norfolk Commanders - Richard Bronish
San Antonio Texans - Ethan Guevara


What is required of a GSL team owner?

As a GSL franchise owner, you are responsible for the logos, wordmarks, uniforms, and field graphics for your team.
You cannot use existing logos for your team (we will check via google reverse image search); logos must be original.
During the season, you will need to provide a uniform schedule for each game your team plays, so your team's uniform can be displayed for each game.
Also, you will need to provide a field design schedule for your team, if your team uses multiple field designs.
If you don't provide a uniform or field schedule, GUD members will choose your team's uniform and field design on game day.


I see a season is already underway; when will the next season start?

The current season on display is just a demonstration of the league.
The teams shown are all teams created and owned by GUD members for the purpose of showing how the league will work, and how team and game data will appear on the website.
The next season will likely start in February of 2021, after the conclusion of the NFL season, which is the busiest time of the year for the GUD.
Tentatively, the start date for the inaugural GSL season will have the first week of games scheduled for Sunday February 21, 2021.
This date is subject to change, based on changes in the NFL schedule, but the GSL is planned to start two weeks after Super Bowl LV.


When is the deadline for applying for a GSL franchise to be included in the next season?

If you would like to be a part of the 2021 GSL season, you will need to complete your initial application by January 10, 2021.
Your team logos, wordmarks, uniforms, and fields must all be complete and approved by January 31, 2021.
Lastly, your GSL franchise fee (in the form of a GUD donation of $20) must be received by January 31, 2021.
On February 1, 2021, no more teams will be accepted into the GSL for the 2021 season, as we need time to set the league schedule, convert all team images to the GUD templates, and prepare the website for the season.


How often will GSL seasons take place?

For now, there is only one season planned for 2021.
The frequency of future seasons will depend on the popularity of the GSL, but it is likely that there will be a single season per year in the spring or summer, opposite of the NFL and future XFL, or spring league seasons.

Something I've gotten a few questions on, is if there is a one helmet rule. The answer to that question is no. You can have as many helmets for your team as you would like.

However, there is a limit to the number of uniform combinations your team can have (combination is a helmet/jersey/pants/socks/cleats). Your team can have a maximum of 10 total uniform combinations for a single season.

In the sprit of transparency, I'd like to share how game simulation currently works for the GSL. After the 2021 season, I may re-evaluate how I do simulations, depending on how disparity in the league shapes up, and if any scores or team records somehow get out of hand.

I like my simulations to be able to be in real life, if technology fails us, so you may notice that all simulation here can be done with a single 6 sided die, and simple math.

Before the season starts, each team gets randomly assigned an offensive, and defensive rank, which varies between values of 1 and 6. These values will not be made public during for official GSL seasons, but for demonstration purposes, these are the current team rankings for the 2020 season:

Team NameOffensive StrengthDefensive Strength
Las Vegas Outlaws36
Los Angeles Express13
Louisiana Royals26
San Diego Breakers51
St. Louis Brewers41
Washington Stars24

These values won't change throughout a single season, but would be expected to change from year to year (this is outlined below).

The above values are then used to simulate a game. The easiest way to explain the simulation, is through an example, so I will use the Las Vegas Outlaws at San Diego Breakers as an example game.

The rankings for each team are as follows:

Team NameOffensive StrengthDefensive Strength
Las Vegas Outlaws36
San Diego Breakers51

The first thing to do, is to calculate the away score. For this, I need a simulated "dice count". By dice count, I mean, how many "dice" (or random values, 1-6) the team can "roll" and sum up to get their score.
Each team starts with 10 "dice", but this value changes, depending on team rankings. The start amount is 10, but 1 die gets added per offensive rank, and 1 die gets subtracted for the opposing teams defensive rank.

For the example, the Outlaws have an offensive rank of 3, and the Breakers have a defensive rank of 1. The number of dice the Outlaws would get can then be calculated as:
10 + 3 - 1 = 12 "dice" to roll

The score for the Outlaws can then be calculated, by simulating a roll of each of these "dice", and then summing each roll.
My example roll comes out to a sum of 40. This is not a final score. It must be adjusted, so that it is possible for a team to roll a 0 (for a score of 0).
To do this, I subtract the total number of dice from the roll total, which in this case is 12. So the score is adjusted down as: 40 - 12 = 28. This score is still not a final away score; there is further adjustment to get to later.

Doing the same process for the Breakers, we note that the Breakers have an offensive rank of 5, and the Outlaws have a defensive rank of 6. The number of dice the Breakers would roll is then calculated as:
10 + 5 - 6 = 9 "dice" to roll

The simulated roll comes out to 35. Again, we must subtract the number of dice rolled, so this gets us an adjusted score of 35 - 9 = 24.
There is one more score adjustment for the home team, and that is home field advantage. Experts in betting typically move the line on average, with all else equal, 3 points in favor of the home team. So I add 3 points to the home teams adjusted score, to factor in a home field advantage. So the breakers adjusted score comes out to:
24 + 3 = 27

So now we have a score of:
Outlaws - 28
Breakers - 27

The Outlaws have officially won this game at this point, but I also factor in another final score adjustment, based on the total offense, and total defense ranks of both teams in this game. I do this adjustment, because, say both teams have good offenses, and bad defenses. We'd expect a higher score for the game on both sides. On the flip side, if both teams had good defenses, and bad offenses, then we'd expect a lower scoring game overall. So I calculate total offense minus total defense, and use this as a point adjustment for both teams, in the following manor:

Total offense = LV(off) + SD(off) = 3 + 5 = 8
Total defense = LV(def) + SD(def) = 6 + 1 = 7

Score adjustment = Tot(off) - Tot(def) = 8 - 7 = 1
I add this number, 1, to each teams score, as a way to adjust for the fact that, in total, in this game, offenses are better than defenses, giving me a final score of:

Outlaws - 29
Breakers - 28

In this game, the change wasn't too dramatic, but you can imagine, the change would be larger for a game between San Diego and St. Louis (which would be +7).

There is one final score adjustment I do, to remove improbable, scores.
We would not expect to see a team ever score 1, or 4 points, and a few other "uncommon" scores, so if a team scores, say, 4 points, I change their score down to 3 points as a final score, UNLESS, this changes this outcome of the game. So if a game ended 4 to 3, I would not want to change the score to 3 to 3, but instead, I would change the score to 6 to 3.

One other instance we may run into, is overtime. In overtime, each team gets a single dice roll. The higher roll wins. The difference between the rolls determines the amount of points the winning team would get in overtime. A difference of 1 through 4 would give the winning team +3 points, or a field goal to win in overtime. If the difference is 5, then the winning team gets +6 points, or a touchdown to win in overtime. If both teams get the same roll, then overtime continues. If both teams tie on a roll of 5+, then each team gets +3 points (both teams scores a field goal first possession), otherwise, no points. We roll again, and if different, points are awarded to the winner as previously defined. Otherwise, if both teams are still tied, then the game ends in a tie. In the playoffs, we would keep going until both teams are not tied, and we have a winner.

And that is the full simulation. If anyone is interested, I have source code in PHP.

This is the simulation method that will be used for the 2021 GSL season. Simulations happen automatically 3 hours after the posted game times, and the scores are posted immediately after simulation. So there is nothing I can do to manually simulate games, or alter game scores.

In the future, I could adjust this simulation method, or use a new method entirely. If I make changes, I will post them here.

Some other things I'd like to add on the topic of simulation, are figuring out the lines, and over/unders for each game, since these things are easily calculated for each game (and may be something I post from week to week going forward).

Using the previous game example, the average amount of points that can be simulated for the Outlaws would be:
12*((sum(1..6)/6)/2)-12 or simply 12*(3.5)-12 = 42-12 = 30

The average amount of points (including home field advantage) simulated for the Breakers would be:
9*((sum(1..6)/6)/2)-9+3 or simply 9*(3.5)-9+3 = 31.5-9+3 = 22.5+3 = 25.5

The line would then be the difference, and the over/under would be the sum, so we'd have the following for LV @ SD
LV -4.5
o/u 55.5

Las Vegas would be 4.5 point favorites in this game.

One thing I've yet to figure out how to calculate is win percentages. Mathematically, and programmatically, I know how to perform the calculations , but I'm not sure I have the computing power to perform those calculations. I'll have to do a test run and see what I can get in return.

Policy Change Announcement:

Once your team's logos/wordmarks/uniforms/fields have been put on the site, and you approve them, the submission is final.
If you want to make updates to your team after this point, you will have to wait until the next GSL season.
It takes a good amount of time to get teams' images up on the site, so making changes to an already submitted team takes time away from other teams, and other work for the GUD.

I forgot to include this in the about page originally, so I've posted it now.

Notes on the 2021 GSL Season

Hello everyone,

I have a quick policy announcement to make, and I also want to go over the timeline for the 2021 season.

This is something I forgot to add to the about page originally, so I've added it now, and I'm making sure the message gets out, so I'm emailing all league members. New policy is as follows:

Once your team's logos/wordmarks/uniforms/fields have been put on the site, and you approve them, the submission is final. If you want to make updates to your team after this point, you will have to wait until the next GSL season. It takes a good amount of time to get teams' images up on the site, so making changes to an already submitted team takes time away from other teams, and other work for the GUD.

For future league updates, please reference the GSL forum, which can be found here:
https://gridironuniforms.forumotion.com/f8-the-gridiron-uniform-database-simulation-league-gsl
Feel free to create an account, and post in the forum as well. This is a great way for league owners to interact with each other.


Next, the timeline for the 2021 GSL season. If you're receiving this email, then your team has already been given primary approval to enter the league. The deadline for primary approval is January 10th, so once that period has ended, the number of teams in the league will be just about set, and I can get a head start on creating a league schedule.

The deadline that's important to current league members is the January 31st deadline. By January 31st I'll need two things: 1) all of your team's logos/wordmarks/uniforms/fields 2) franchise fee, in the form of a $20 donation to the GUD. If I don't have both of these things from your team by this date, your team will not be eligible for the 2021 GSL season.

The following teams have completed all league entry tasks, and will be included in the 2021 GSL season:
Memphis Comets
Norfolk Commanders
Louisville Lightning
Cincinnati Knights
Pennsylvania Keystones
Las Vegas Outlaws
Louisiana Royals
San Diego Breakers
St. Louis Brewers
Wisconsin Stags

The following teams have passed secondary approval, but have not yet submitted their franchise fee:
Baltimore Bluebirds
Los Angeles Express
San Antonio Texans

The following teams have paid the franchise fee, but have not submitted team designs for approval:
Arizona Eagles

The following teams have not completed their team designs (or approved their designs on the website), and have not submitted the franchise fee (to be sent after team design approval):
Atlanta Flying Fleet (missing field design(s))
Colorado Cabras (awaiting approval from owner for images on website)
Minnesota Honey Badgers (awaiting team designs)
Toledo Shadow (awaiting field design(s))

Again, the deadline is January 31st, so there is still plenty of time, this is just a reminder.

I still plan to have the 2021 season start February 21st (or possibly Thursday February 18th). If I can get a schedule created by February 11th, I'll have the season start then. Things may change, depending on my personal situation. My wife and I are expecting our first child at the end of February or the beginning of March. If things change, and the baby comes earlier than expected, the season may be delayed, until I get a handle on the new life I have at home. The good news is, once I have the schedule set, the rest of the league is automated, so I won't have to do anything, other than update uniform images and fields for the week on the website.


Next in the agenda, is regarding awards for teams making the playoffs, and winning playoff games. As stated on the league about page, the franchise fee is a yearly donation required to stay in the league. I'm hoping that our new ads go well, and I can reduce, or eliminate the franchise fee altogether for future seasons, so post season awards will be based on a percentage of whatever the franchise fee may be for 2022.
- 2021 GSL Champion (no franchise fee for 2022 season)
- 2021 GSL Runner up (75% off franchise fee for 2022 season)
- 2021 GSL semi finalists (50% off franchise fee for 2022 season)
- 2021 GSL playoffs participant (25% off franchise fee for 2022 season)

For the 2021 season, if no new teams were to be added to the league, there would be 7 playoff teams. If more teams join the league, I will add more playoff teams as appropriate.


Another note on the 2021 season; I'll randomly select team strengths after the January 10th deadline. These are not something I'll be giving out as public information. Strengths for a team in one year will not carry over to the next year; I will completely re-set them. So, the best team from one year may end up being the worst team the next year, and vise-versa. I'm doing this so that every team starts out on an even playing field from year to year, and has a chance to win a championship, regardless of their previous seasons performance.


Okay, this email went longer than I expected, but I think I've got a bunch of important information out here.

Thank you all for contributing to the GUD by joining the GSL, and we are looking forward to a great 2021 GSL Season!

I just sent out a league wide email through a group I set up in gmail. I'm just curious if anyone got it (I should have included myself on the email). Also, I BCCed everyone, so I also want to make sure you can't see anyone else's email addresses with the message.
