Drop Austin Collie or Michael Crabtree for Devery Henderson?

I've already dropped Parker (he's still injured) and I have McGhee on the trading block. He's hardly a factor any more. Not even an appearance in last week's game. Henderson is more and more becoming a Good target for Brees. Mendenhall and Rice are both proving very productive additions. (I would choose Mendenhall over Rice and get Henderson in the game at W/R by replacing Parker. My big mistake was trading him off early and living now to regret it. Trade your Back up RB's before you get rid of the receivers. If I had to release a receiver, I'd move Austin Collie. I'd also be trying to get a more effective RB backup than either that you have.
