Peterson is Peterson, and although people need to hold off on fitting him for a gold jacket just yet, his potential is off the charts. Cromartie might be a hair older, but he can still run and always has had dimensions to lock up with the Y2K wideout. Although I'm kind of cheating here by bringing a third guy into play, Mathieu is too good to just ignore. Yes, he's recovering from a serious knee surgery, but Cardinals GM Steve Keim just said the Honey Badger could be back for the opener. If he can indeed return to good health, Mathieu gives Arizona extraordinary depth in the coverage department.
