Ever versatile, Mathieu thrives in the slot.
Mathieu can play cover safety as well as anyone in the league, and can even move to outside corner in a pinch, but it's his slot play as much as anything that makes him special. Mathieu is an aggressive gambler who baits receivers into believing they have a chance at the ball, only to close in at the last millisecond with his freakish athleticism and ever-improving game intelligence. He'll whiff once in a while, but Arizona's coaching staff encourages him to let it all hang out, and when he's healthy, the Cardinals reap the benefits. There isn’t a receiver in the NFL he can't keep up with on a step-for-step basis.
