I type this not to bash Crean, but to shed further light on those winning percentages. If you go to sports-reference.com and do a little research on Strength of Schedule, you will find that IU consistently played one of the toughest schedules in the nation under Knight. That is not the case today.
For example: Knight's IU teams faced a Top 5 SOS 16 times in his 29 seasons along with 4 more seasons with a Top 10 SOS. Knight's 3 worst SOS's were 51st, 49th and 37th. Crean's last 3 SOS's have been 63rd, 52nd and 58th (using sports-reference for consistency)
RMK's S.O.S. was considered better but as we all know, it's built off a lot of teams in the 75-200 range. Feel free to call Crean stupid for scheduling 300+ ranked teams because the outcomes of games versus 75-200 would be the same as we currently have. But comparing schedules, I don't look at the RMK pre-conference schedules and think "those are better than what IU plays now". So the winning percentage fact still remains.
