Rice is a tricky one for me. I'm not too worried about the injury from last year, but his siutuation in Seattle, in the short-term, worries me. Shaky QB play, likely subpar overall offense, and Zach Miller and Mike Williams getting some decent targets. Rice is likely the deep guy, so he won't be direcetly fighting Miller and Williams for targets, I'm just thinking that opportunites may be limitted for all of them (small pie to divvy up).
For 2011, I think I like everyone on that list you mentioned more than Rice. Going forward to 2012 and beyond, I don't feel that way... situations can change quickly and Rice is talented.
I'd feel good with Rice as my WR3 and still think the upside potential is good for 2011, but as my WR2 I'd be a bit worried. I'd want to have some good depth behind him at WR3 and WR4 to serve as a safety net.
