Can We Just Admit that Marion Barber isn't Overrated?

I mean c'mon my cousin and uncle are huge Giants fans and say that the Barbarian is a hell of a talent. Even if you hate Marion Barber, how do you justify that 70 yarder he broke for a TD on Sunday? I mean granted he has a great offensive line, you still have to make key reads on where the defense is going and Marion is one of the best in the league at this. Barber is averaging over 100 yards a game (rush+rec) and 1 td (a game). The Jets also have an excellent offensive line and look how Thomas Jones is doing? pretty weak 3.8 yards a carry...with the longest run at 16 yards (look it up on ESPN). Thomas hasn't broken any runs for over 16 yards.
