Every year USC is supposed to be really good, starts off strong, and then poops down their leg the second half of the season and maybe wins eight games. That, and they lost the #1 overall pick in the NFL draft along with two other day 2 picks and about 15 other transfers including a 5-star QB and they still can't play defense.
Iowa lost all-world DB DeJean, their top defender in sacks (Joe Evans), their #2 tackler (Nick Jackson), and their #4 tackler and #3 defender in sacks (Logan Lee). I don't see their defense being nearly as good, and the offense is still Iowa.
Nebraska hasn't had a winning record since 2016. They have to prove they can win first. They played two teams last year who finished in the top 25 and one finished 24th.
I have no idea how Northwestern did what they did. 106th in points scored, 42nd in points given up, 68th in sacks. Have to find a new starting QB.
Other teams picked to finish with a similar record as UW have just as many question marks.
