Sanders was probably the best cover CB ever....as well as one of the most explosive ST players.
I think Sherman is already a better CB....he's much more physical and plays the run way better than Neon ever did; Sherm will throw a shoulder...those 3 tackles on that youtube vid were the only shoulders I've ever seen Sanders throw into someone.
I disagree a cover corner is much more valuable then a run stopping corner. Granted I love Sherman and he's a pretty solid cover corner himself but if I had to choose between him and Deion and his prime, I would take Deion. People love to talk about how Deion didn't tackle, but he didn't need to, his guy was never open.
I love Sherman's ability to help against the run but it's a bit overstated. He made what maybe 7 or 8 tackles last season on running backs?
