There's no doubting Tyrann Mathieu's natural ability as a playmaker. With the ball in his hands, though not especially explosive or fast, his open-field elusiveness is special.
However, Patrick Peterson is an elite return man, so it's highly unlikely that Mathieu unseats him from that role in Arizona.
He's undersized for the cornerback position, but he should be on the field in the nickel package, which is becoming a more prevalent necessity in today's NFL.
If he intercepts a handful of passes, takes a few to the house and makes the most of any punts he fields, Mathieu has a chance, albeit a slim one, to win Defensive Rookie of the Year in 2013.
