But, dude, you take both the starting corners out, especially the type of corners Jabari and Tracy are, and then put a combination of Usama-Jenkins-Gay playing corner, of course your pass defense is going to suffer, regardless of who plays FS for you. None of the replacements at CB can cover routes or re-route receivers like Jabari and Tracy can.

I don't know if Sharper is over-rated or not, or who is over-rating him, but compared against the other FSs in the league, he made the plays when he had the opportunity and the others didn't. That's it.
How much he gets paid, that's not for me to decide. It is not my money, but I am not going to say he does or doesn't deserve a certain amount of money because he plays with better corners or worse corners.
