I haven't looked at any stats for Rice, but I probably would be. You're going to take a 9m dollar cap hit if you move Rice however, and I'm not giving up a first for him, so I'm not sure it'd actually be worthwhile on your end.
Hmm when you put it like that...
Evan Moore is still available. His blocking stats suck but he's a good receiver. Given his age and small contract the price is low.
