Cover charge: Troy Vincent and Bobby Taylor help make cornerback the deepest position on the market, but the Eagles' duo and other name players might not find a big payoff in a changing business climate.(NFL Free-Agent Preview)

But it wouldn't have clicked with clockwork precision for so many years if Troy Vincent and Bobby Taylor, a pair of super-sized, physical cornerbacks, weren't able to rough up receivers at the line and bump them off their routes.

Sorry, fellas. What have you done for me lately?
