Alex Grinch says his disappointing tenure as Southern California’s defensive coordinator the last two seasons has given him even more incentive as he begins his new job as Wisconsin’s safeties coach and co-defensive coordinator. Grinch was fired at USC with two games left in the 2023 regular season, one day after his defense allowed 572 yards in a 52-42 loss to eventual College Football Playoff runner-up Washington. “What happens is when you don’t have the success that you expect, that you can circle that and highlight that, and it leaves a bad taste in your mouth, but it also creates a chip on your shoulder,” Grinch said Wednesday.
