Hurley and his staff have every reason to be confident in their coaching abilities and their work is proof of their elite coaching abilities for sure. I also think Hurley needs to be more flexible at times and not think "teams from 2023 and 2024 were able to do this so I know this works" and find what works, or at least what works best, for the current roster he has.
As for giving more rope to the bench players, I wish he did, too, but I completely understand why he didn't. It seems like whenever he brought in the bench guys, the other team would go on a scoring run and remove any lead or increase their lead. The bench players need to show some positive impact when they are in the game, and Hurley kind of called them out in the post game press conference after the Georgetown game in Gampel. He mentioned earlier in the year about how UConn will wear teams down with their intricate offensive sets, by running opposing players off the 3 pt line (not pressure D to cause turnovers), and with their bench and depth. That is not happening because whenever the games are tight he is dialing back the rotations and not including the bench.
I think you are both correct. There are personnel and scheme mismatches. He cannot have this team play defense they way he would prefer. It's just too easy to isolate UConn's defenders and play 1v1 because the other defenders off the ball are not a few steps off their man which would leave them in better position to help. Mind you, this doesn't mean give shooters enough time for a slow release 3 pt shot on a kick out pass either. I know UConn lacks the athleticism to help and recover consistenly, but the lane is wide open and opposing players can comfortably dribble and deliberately take the UConn defender 1v1. It's been an issue this year, but this issue persisted last year, too. I noticed it in Maui and in the Providence game at Gampel last year when Providence build a 14 pt lead and players like Ryan Mela, Jayden Pierre, and Wesley Cardett Jr. were cooking our UConn defenders 1v1.
