Penn State experimenting with defensive tackle rotation?

Over the last several seasons, we've talked about how Penn State has tweaked its usage of defensive linemen. The defense went from all-out pursuit of the quarterback with former defensive coordinator Brent Pry to a more contained rush focused on keeping elusive quarterbacks in the pocket. At defensive tackle, the game plan was to play two players of similar skill at each defensive tackle position and have their position (one technique or three technique) determined by which side of the field they were on and the formation they faced. However, after hiring defensive line coach John Scott Jr, the team moved to a different approach. This past season, with senior defensive tackle PJ Mustipher going all-out for his NFL bid, he bulked up to 325 pounds to play a more pure nose tackle role in the defense. This move solidified a team split in the group to more traditional roles and defined their responsibilities therein. While it wasn't only because of Mustipher, the big-bodied defensive tackle allowed the team to make the switch.
