Right now with who they have..if Leon is good to go, throw him back there. Why not? If not, Brad Smith did pretty good imo, I think he would be fine. That's his role on this team, he's yet to step up as an actual WR so this is where you use him.
Same thing with PR...I want Leon back there if he can do it like he used to, it was great when he actually changed field position for us and not just moving it a few yards like Cotchery and Leonhard did.
