DeJean is one of the five finalists for the Nagurski Award as the best defensive player in college football, and he is also the Big Ten's leader in punt return average — despite his signature play of this season, an apparent game-winning touchdown return against Minnesota in the game's closing moments — being overturned on a controversial ruling from the officials that DeJean had made an invalid fair catch signal before running the punt back.
