While it's frustrating to have a player claimed by a team which doesn't want to trade for him, I realize that it happens in the real world and is part of the game.
I also know that putting one of my players on revokable waivers will put me at a disadvantage with the team which claims him, but there's a reason why I waived him (demote, remove from 40, get out of next year's contract, etc.), so I'm not expecting to get 100% "fair value" for him.
