Slight disagreement...the problems became obvious a game earlier...during the Thanksgiving weekend game against KSU/Klieman in his third year. ISU's offense was manhandled in that game, and then just completely overwhelmed in the following ND game. Hall under 60 yards in both games. It was a big time red flag that the offense development was significantly lagging. Campbell did nothing. Covid just delayed what is now happening by a year.
I like what a couple of folks said in the threads earlier this week. Campbell isn't coaching to win games; he's coaching to prove that his Toledo philosophy can work at the P5 level. Well, it marginally works when the team has NFL-level talent at a few skill positions. One poster astutley pointed out that Campbell was doing the transfer thing at Toledo well before eveyone else was (kind of like Hoiberg at ISU). He'd get a number of 5th year players from P5 schools every year, so his teams were more athletic than the other teams he played and his system could work.
