If all this is over the word "bust", then let's set that aside since it's silly to argue over words.
If he came anywhere close to the expectations of his $, then he would have at least been a great bench option whenever Wagler or Bos rested or were hurt, and Wagler certainly could have rested more. The NCAAT was 2 months away when Bos got hurt, so his lack of playing time then tells me that the staff didn't have much hope at that point, and I don't get the impression they tried hard to retain him this offseason.
It could certainly be that he was good, but...
- was objectively a bad fit or the staff couldn't figure out how to use him effectively
- he's a slow learner
- he mentally shut down
- the time he missed at the beginning was just too much to reasonably expect him to overcome
All these are part of the recruiting/coaching equation except the last, though even that one is hard to separate from his talent, fit, and ability to get up to speed.
