macunit voted on a poll: Does Playing the Matchups/Benching Guys Work?
Every only league I play in lets you keep the player if they are traded during the season. You just can't trade them and if they're dropped, they're gone. And since players can be traded too the leauge, it makes waiver priority or FAAB worth more. But I like only leagues since I can play in 10 or 12 man redrafts with people I know from other leagues instead of having to fill up a league to 20 or 24. Good luck finding 24 owners who will stay active all season long in a redraft league.
