IMO is a more dominant pass rush with front 4. If the front can penetrate and get pressure this will be the key to getting off the field on 3rd down. Time and time again last year ND allowed drives to continue because the quarterback had ALL day to find someone. For anyone who thinks it's not a game changer please see Von Miller against the Patriots in the AFC champ game. Yes ND doesn't have a Von Miller but they have Trumbetti (who slimmed down), Daelin Hayes and big Isaac crashing the pocket.
