I think the biggest positive is how the game itself played out.
Let me explain. By holding onto the win after the three setbacks (Floyd’s fumble, the safety, Mavre’s TD run), it teaches the players to dig deep and work even harder to close out the game. If we had blown out Purdue, the players probably don’t learn this lesson. The two interceptions gives the defense confidence that they can do it again in the future. Finally, winning using a simple game plan with no trick plays sends a message that we can win if we focus on fundamentals.
Another positive is how the Michigan game played out. Robinson’s performance should be a wake-up call to the defense to stick to their assigments and make tackles.
