I personally love Bell's heart and effort. The guy brings it on every play and runs his heart out. But he just doesn't have the burst, the lateral agility, the vision or the feet to succeed in the NFL. The comparisons to Daniel Thomas are obvious but Thomas at least had elite feet for his size. Problem is he goes down to easily for a big guy because he doesn't have natural power or run with passion. Bell is tremendously passionate, but without the talent he's basically Eddie George at the end of his career. He should have rocked up and become a linebacker, imo.
Christine Michael is a headcase but you've got a much better chance of turning his brain around and getting something out of his top shelf talent than you do fixing Bell's physical deficiencies.
