The Gridirion Uniform Database Simulation League

The Initial Application Period for the 2021 Season Has Ended

The GSL has reached a desired number of teams for the 2021 season, therefore we will not be accepting any new applications for teams in the 2021 season.

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, 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.

NOTE: 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.

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.

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 6, 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.
