I play in three football leagues- no other sports
1- A keeper I run myself- 12 teams, PPR. Keep three players each year- draft pick cost increases each year. Draft is hybrid snake/order of record. 17 roster spots plus IR
2- A 10 team, 2 QB league, half point PPR. Snake draft- fairly standard
3- A 14 team auction league. PPR. No kickers or defenses. $200 budget. 16 roster spots. You can spend your auction budget on 5 players if you want. At the end of the auction, those with roster spots draft "free" players that are left to fill out the roster. 224 players are rostered each year with no kickers or D- fun stuff.
