Keep the bashing coming. It appears as though many of you haven't actually watched McCoy play, but are just going by the stat sheet. The guy is good, but has been very fortunate throughout his time in Philly. He's had the benefit of having one of the best o-lines as well as some of the best offensive coaching in the league throughout his career. Look at how any of the backups have done while he's been there...Brown, Sproles, etc. And not to mention, he's got quite a bit of mileage on him now.
As for Fred, he's never had a good o-line despite what the genius upthread is saying. In terms of offensive acumen, Gailey is the only decent coach he's had. Compared to Andy Reid and Chip Kelly, what he's dealt with is laughable. He outplayed Lynch while he was here, who is now considered one of the best in the league. He outplayed Spiller. And he will now outplay the latest hotshot here to take his job.
McCoy had the luxury of running through gaping holes and getting to the second level where he did most of his damage while in Philly. He will not have that here. I hope he does well, but I'm just warning many of you to temper your enthusiasm. You may have the same gripes with McCoy as you did with Spiller. Too much dancing behind the line and not enough powering through. Whereas someone like Fred knows when to put his head down and drive into a tackler, but is also elite at making the first guy miss. Not to mention he's a better blocker and receiver too. No, he doesn't have the top end speed as some, but he never has. That's not his game.
As for him losing a step or whatever, please keep in mind that he has less career carries than McCoy. A fact easily overlooked by the resident ageists on the board.
The running game will be improved with Roman and Kromer here now, and the biggest beneficiary will be Fred.
