He was solid that year (believe he was Big 12 FOTY), but his performance in the tournament was absolutely not indicative of his body of work.
The bottom line with Hunter is that he came from absolutely nothing. Both parents died when he was young, and he was raised by his older brother. He needed money, and that's why he came to Austin. I'm sure he said all the right things about the staff and program, but by all accounts he was very happy at ISU (especially being 4-5 hours from home) prior to learning what kind of bag was out there. He was projected as a fringe NBA guy at best, so this was his opportunity to make money playing basketball that he could use to stabilize his family and at least give him some options at a better life.
In my experience people just don't perform at their best when they're only doing something for money. Maybe he had a good connection with Beard, but obviously he's not part of the equation any more either. Regardless, he went to Texas for primarily financial reasons, and then the program shifted suddenly under his feet. What he signed up for isn't what he's getting at this point. I think a lot of people in his situation would find themselves adrift for lack of a better term.
