I think this is a very good team and would be quite surprised if you didn't make the playoffs.
QB: Great two guys to have. Cutler is a high-upside backup and the yardage bonuses could really add value. Wilson should get it done with his legs even when he's not getting it done through the air, and IMO is a top-10 guys.
RB: How in the world did you land Sproles and Bush so late in a PPR league? Wow. This is an insane group of RB's, IMO. Richardson has a ton of potential as a bye week fill-in. I think I'd hang onto Woodhead; if you really want Bell, drop Kendall Wright.
WR: Here's your hole. You're obviously in great shape at WR1 (how was Megatron still there at #15?!), but your other guys are all of the high-upside/relatively unproven variety. Tate, Givens, Thompkins, and Hopkins are all guys I've targeted in other leagues as WR3's or late-round value picks and I LOVE all 4, but I'd be a bit uneasy relying on any of them to be my WR2 at this point. Hopefully for you (and me), at least one of the bunch breaks out and becomes a star. Wright is a step below this group, IMO. He has talent, but his QB situation is shakey at best. If you're going to drop anyone to pick up Bell, it should be him.
TE: Nicely done. PPR monster. I like the 1-TE strategy. Past a certain point, TE is a pretty deep position; pick up a bye week fill-in when you need one.
Hope that helps. Here's mine: http://www.fantasyfootballcafe.com/forums/viewtopic.php?t=536483
