I usually respect FJ's call on RB prospects, but in this case I disagree. I don't see how you can question Ameer's fluidity or elusiveness. Those are two of his best traits. Not only that, but he's probably tops in the whole RB class in those categories. You can pull up pretty much any highlight reel of his college days and see multiple examples of him making people completely whiff in space.
I think he's a better pure athlete than Gurley or Gordon. Are they bigger and faster? Yes, but I would say he is more athletic in general. The fact that he crushed every drill at the combine besides the 40 supports that. He reminds me of guys like Harvin and Beckham in terms of his fluid movement and explosiveness. Obviously he plays a different position, but he has that same effortless athletic style.
