The premise of all the Kiko-McCoy trade talk is the Bills getting some line help and an upgrade at tight end. But if they do that, they would have been fine sticking with Fred and whoever else they got in free agency. Not to mention still having Kiko.
Not sure if people realize that McCoy has played behind a top notch oline his whole career and has been coached by smart offensive minds. Darren Sproles actually had a much better rushing average than him last season. I can't think of another running back who has been as fortunate as McCoy. He's good, but he's not as good as most here think.
Put him on the Bills last year, and how do you think he would have done with our 32nd rated offensive line? Lower your expectations about him being the difference-maker here because it's not going to happen. The offense will still suck and be carried by the defense again. But we do have an easier schedule, and the defense (barring injuries) has the potential to be even better under Rex, so anything's possible.
