There is only one rule in this league. Every team must have an active QB, Kicker and Punter on their roster for the regular and post season. Other than that feel free to experiment all you want. I like to see players make plays. It doesn't matter to me how those plays are made.
Off balance trades are allowed. Older and slower players have too high trade scores in my opinion. The only way to trade them fairly is to allow off balance trades.
If you want to change the team name or logo I don't mind just keep it on theme. I will rename some players after they are drafted to their team. If you want them to have a different name feel free to change it before late free agency starts.
Please don't change the stadium size. I assigned 70,000 to every team. My idea is to add stadium size as a reward to teams that win. If you win your division I'll add 1,000 to your stadium size if you win the conference I'll add 5,000 if you win the league I'll add 10,000. The max you could get in a season is 10,000 they don't add on top of each other. Stadium size doesn't have any affect on the game. I just think it's a cool reward for winning. If you win the league I'll also add the year you won to your team logo.
