Last year he put up 2,711 yards and 29 touchdowns through the air, setting the school single-season record for scores and leading the league in both categories.

Mary Hardin-Baylor Athletics

Standing in a league of his own, Autenrieb is the national active leader – at any level – in interceptions with 27 career picks. No other player at any division has more than 19.
