That punt block was a glorified turnover that led DIRECTLY to points. He didn't lose the game by himself, but once that happened, our win probability dropped significantly. IU is a team that desperately needs help to win games, they lack the offensive explosiveness needed to win shootouts. Miami gave them a TD that they didn't have to earn.
There's absolutely no way the call was "Hey Bauman you're just going to let a guy run right past you while you have your thumb up your butt and you do absolutely NOTHING to stop him" . He just didn't give a crap and acted accordingly. He's not a freshman thrown out there last minute, he's a GROWN MAN. He knows better, and still gave absolutely zero effort. That's the kind of effort that got you punched out in the locker room back in the day.
