I like the idea of a Philly guy over Cohen and, if healthy, I think Clement will have earn the majority of the work over Smallwood. There's risk that he won't be able to get/stay healthy or that the Eagles bring in someone else (a lot of McCoy buzz out there) but on the chance he's the lead dog in a very nice offense, I think he's the move.
All of those RB's over Cohen work for me. For this weekend Smallwood is good but for season long Clement, Powell, Hines then Smallwood is how I would rank them. The main problem with the Philly guys is that they could get knocked down if Philly trades for McCoy/Coleman or ???
I wouldn't want any of the WR's over what you have but I could see going after Clement, Hines, and/or Smallwood......probably in that order for me. As far as who to drop, Collins' usage has been terrible and it appears Buck Allen has taken over. I am not sure if I could actually drop Collins but that is the way I would lean. Cohen would be a close second (and really may be the first if I just couldn't pull the trigger on Collins) and Miller third. I am not saying to drop all three...just that is my order. I probably would pick up Clement for Collins/Cohen (still can't decide).
