"It was just a cool place and it felt right for me."
At 6-3 265-pounds Allen is considered an athletic lineman who excels at run blocking and pulling, and one that can play both on sides of the ball.
"Dejon Allen shows his versatility by playing on the offensive and defensive line," said Scout.com's Southern California recruiting analyst Brandon Huffman. "Allen looks more natural as a defensive end with an explosive first step and burst of the ball. In addition, he shows a good swim move and balance. Offensively, Allen is a natural knee bender that will need to add weight to his frame for the next level. Allen prefers to play offensive line."
Allen chose ASU over Pac-12 foes Arizona, Utah, and Washington, as well as Boise State and SMU among others.
The linemen is part of a talented Dominguez team who already has six players with Division I offers. The Dons finished 10-2 last season and according to Allen could have another solid campaign in 2011.
"We should have a good season but we have to work on some stuff," Allen admitted. "We need to work on our passing game and replace some safeties. But we can have another good year."
