No way, Rex's D calls for as many decent CBs that you can get. While Cro isn't Revis, he's arguably the best #2 CB in the league.
Sanchez (and Schotty) have to learn how to use Plax. He's not going to beat people, but he will get body position. Back shoulder throws, fades, stop routes. That kind of thing.
first thing you should do when a new corner comes in, test him deep, especially if you can get him 1 on 1 with a holmes/plax. Doubly so if his name is Allen.
Plax isn't fast off the line.. but he never was. His game is outmaneuvering corners and using his size. We don't use him for those things though.. really don't use him to his strengths at all. Kind of a running theme with our offensive players.
Just thought about that I think this off season if we get a play making safety then Cro can go we would just need a new nickle back so it all depends as Wilson is a luxury at nickle back for us
