Joey O'Brien had a strong first career start for Notre Dame, finishing with five tackles and a half sack in the Irish's win over Purdue.
After the game, the freshman safety praised the pass rush that helped drive Notre Dame to six sacks against Purdue. It was the kind of defensive performance that makes a young secondary player's job easier, and O'Brien's production showed he was part of the action as well.
Notre Dame's pressure set the tone
The six-sack output was the clearest sign of how disruptive Notre Dame was up front. When a defense can create that much pressure, it changes the entire feel of the game, forcing the opponent to work faster and giving the secondary more chances to finish plays.
For O'Brien, the outing offered an encouraging start in a meaningful spot. A freshman making his first career start and contributing 5 tackles plus a half sack suggests Notre Dame is willing to lean on young defensive pieces when the matchup calls for it. It also points to a defense that can win in more than one way, with pressure up front and support from the back end.
The immediate takeaway is simple: Notre Dame's pass rush was the story, and O'Brien's performance helped underline it. After the Purdue win, the Irish came away with both a major defensive number and a young safety who looked ready to contribute right away.
