Good man/press CBs are unlikely to be found just coming out of college. Probably a major reason for this void is the way college CBs are trained today to stay up with their man. In the NFL, it is mandatory that these type of CBs to be successful must be able to back pedal and quickly change direction (any direction) when needed. Colleges are now typically not teaching backpedaling..........they are teaching side shuffling.......a technique which makes it almost impossible to acutely change direction opposite of the direction they are facing. Good NFL receivers are savvy enough to take advantage of this technique every time.
