I'm not sure if he's lost his hunger, desire, edge, etc. I just think he's flatly a bad coach. The years we've been good we've had some exceptional talent. In the last few years, up until this year at least, we haven't had the talent needed to overcome coaching. And in the recent years its compounded with older players, transfer/NIL etc., the physical nature of the college game, we are even more susceptible to upsets.
If he's going to continue with this simplistic style of coaching (only 1 defense, no focus on strategizing for the other team, basic pick and rolls, one on one offense, etc.) -- and I see zero evidence that he will change -- then he needs to build proper rosters with players who can impact the COLLEGE game, not necessarily NBA, whether freshman, transfers, etc. He has to evaluate whether some of the highly rated freshman are gonna impact the game in their first years or not, cause that's all you can count on (one year).
