Wells is great for depth. he is great on special teams and is a solid #2 or #3 RB. Besides.. he has obviously shown improvement and he may show us some more before its all said and done.
if we plan on drafting an RB.. trade Davis.. much as it pains me to say that. he could get us a pretty penny from someone who needs a back I imagine.
Honestly though.. we just arent to that point where trading players for picks is a good idea. any good player we have right now is needed for depth. heck.. WR is our deepest position, and if we got rid of one of them we would be in bad shape there too.
