Fred had a amazing half a year. But since when do we make a guy top 10 for having a half a years worth of work? Especially since you can't help your teams fumbling or being out with injury.
Fred is a great guy, he is a leader in the locker room, he has great work ethic, he is a great pass blocker. He isn't top 10 though but that isn't saying he is bad.
I will say he is a top 10 backup RB, probably the best backup RB in the league.
