Like what? The game in the trenches is a series of helmet-on-helmet battles. Physically.
One thing UNI does to overcome their physical disadvantage is the DL uses hard slants that disrupt blocking schemes and essentially creates a mess, this is 7th grade football gimmick stuff. They have also in the past had the DL submarine OL in order to create a mess on the line, once again 7th grade gimmick defense stuff.
