Have you happened to actually read about the roster turnover at Mississippi State and LSU when these coaches took over...and further, you can include Missouri. Let me break it down for you:
Mississippi State: Lost 8 guys from last years team. 59% of the total minutes and 58% of the total scoring. He brought in portal players and HS recruits. They are 17-9 and 41 in KenPom (last year they were 49 in KenPom and 18-16...so how is this a loss in your mind?)
LSU:
Matt McMahon: only 3 of the 13 scholarship players returned from the prior LSU season. He brought 3 players from his Murray State NCAA team, 4 HS recruits, and 3 portal players. While they are 12-14: they have a win against Arkansas. *This has started to mirror CBJ in Year 1 though*
Missouri: doesn't count in your mind...it's the coach (so does that mean CBJ is just terrible...?)
Penn State: They are 15-11 and KenPom of 48. This is not a fail. They have been a historically below average program. The only two bad losses they have is 2 against WI & @ Nebraska by 9 (in the Big10). They still may make the NCAA tournament. Last time in the NCAA tournament was 2011.
