The addition of four former Pac-12 teams was supposed to bring some offensive firepower to the Big Ten and change its reputation. It hasn’t quite worked out that way. Scoring in the Big Ten did rise in 2024 after Southern California, UCLA, Oregon and Washington joined a league known more for defense. Point totals went up again last year. But they’ve gone down enough this year that three Big Ten teams already have fired their offensive coordinators. Nebraska dismissed Dana Holgorsen and Michigan fired Jason Beck over the weekend. No. 18 Oregon dumped Drew Mehringer two weeks earlier.
