No awards league. None of the players can be in the HOF, and none can have won an award that season. Someone like Derek Jeter can be used since he is not in the HOF - but only in a season where he did not win a gold glove, rookie of the year, MVP or All Star. Same with guys like Bonds, Pujols, Mariano Rivera. Any HOF player is off the table entirely. The relevant awards are the ones recognized in the WIS search engine. No DH because it requires more managing and requires some half decent bench players.
I also like the idea from ToddCommish of no restrictions other than all $100M players from the 24 advancing owners are blacklisted.
