IMO, free agent pickups or trades should ABSOLUTELY NOT BE ALLOWED after the end of the regular season. To allow it, opens your league up to people who are out of it trying to ship their good players to those in the playoffs. Friends can help out friends, and it creates a mess. In ESPN league last year, the guy didn't lock free agent pickups. I told the commish this was a big mistake and why, and he agreed, and this year he is going to lock it. I like the idea of having to plan your team for the entire playoffs a couple weeks in advance. Pays to think ahead, and also rewards those who had comfortable margins for getting into the playoffs with more time to prepare.
