I've heard James is actually floating around the 190 mark. That 185 pound listing is still the same one from when he was a freshman. James is an offensive weapon, pure and simple. I totally agree that James in a Reggie Bush type role would be perfect for him in the NFL. One thing I think he has an edge over Bush is that James has a low center of gravity. Very hard to get a clean hit on him. With speed and talent like James has, coaches will figure out tons of ways to make him effective in the NFL.
Guys like Jahvid Best and Chris Johnson are exactly big guys either. Speed kills that's all I'm saying.
