I am sure the rigors wore him down, but what really wore him down was his constant losing and the fact his team and his coaching performance were not cutting it anymore. Miami this year has lost 8 of their last 9 games and have a 4-8 record. And if you look at their schedule this year, it's not like they played a bunch of juggernauts, quite the opposite actually.This is not a real surprise. Larranaga is 75 years old and I'm sure the rigors of coaching basketball in the ACC wore him down. Sure, the NIL game is disruptive, but he was one of the original disrupters. A really good coach, but his recent record indicated that it was time to go as he wasn't going to do a rebuild.
Miami was 15-7 at one point last year and were thought to be a team with a Sweet 16 ceiling at that point. They proceeded to end their season 15-17 by losing 10 straight. Do the math. Ever since being 15-7, they are 4-18 since. Sure he added Matthew Cleveland and Kyshawn George, but that wasn't enough to compensate for the departures of Isaiah Wong and Jordan Miller. But going 4-18 going back to last year shows he didn't have it anymore, which is why the Miami admin and others probably pushed him out.
