Serious question...how do you think McCoy would have done in this offense last year? Consider the difference from Chip Kelly to Marrone/Hackett, the difference from Foles to Orton, and most importantly, the difference in the philly o-line and ours. Bryce Brown and Darren Sproles ran free in those offenses too, don't forget. Sproles had a significantly higher rushing average than McCoy last year. Not that I think that's the best barometer, but still. McCoy is a fantastic player. But only if used right. He has to get to the second level to do damage. If he can't do that here either via creative play-calling, or lacklustre line play, he will quickly fall out of favour with the fans here, especially when you take his personality into account.
Just let the season play out. Fred will be the name everyone is calling for to be out there by mid-season. It's always the case.
