Dior Mathis video Thankfully, Dior Mathis chose the Ducks during the Army All-American game. Considering the numerous Duck DB commits this season, and the very young members of the secondary already playing stellar; we will have a great stream of DB's playing for years to come. Mathis is 5'9 and around 170 lbs. He reportedly runs the 100 meters in the high 10.4 range, so his speed alone will help him compensate for his short frame. In the 2011 season, a cornerback duo of Harris/Mathis could be truly great.
