Player ranking and stats
Allen played only one year of high school football, but that single season was impressive; he was named first-team all-state in Florida by the state's sportswriters (the team also included 2010 prospects RB Javarris James (Miami, Fla.), DT Linval Joseph (East Carolina), CB Sam Shields (Miami, Fla.) and 2011 prospect Ohio State senior linebacker Brian Rolle).
Allen took on the challenge of attending a military college, The Citadel. He played sparingly in four games as a true freshman, making two tackles, before redshirting the 2007 season due to injury.
Allen finally received more playing time in 2008, playing in all 12 games, starting six, making 39 tackles, two for loss and breaking up five passes. His breakout 2009 season earned him a spot on the Southern Conference's coaches second team; his 57 tackles ranked second on the team, and his three interceptions and five pass breakups led the squad.
The 2010 second-team All-Southern Conference pick (22 tackles, two INTs, five PBUs) has a build and movement quite similar to those of former Tennessee State star Dominique Rodgers-Cromartie, who was Arizona's first-round pick in 2008. Allen has not been as productive as "DRC" and is not quite as physical, but has prototypical height and similarly quick feet. Those attributes should get him consideration in the mid-to-late rounds.
