UTEP, not Tech. Tech was dumb enough to hire him after UK.
But yeah, he was a fairly hot name. He'd had success, and an upward trajectory, in 5 years as a head man, and he had been an assistant for Bill Self at Illinois, with a lot of success. If UK didn't hire him, Arkansas was probably going to come in with a big offer.
OTOH, if you look closer at his success, you can see holes. His UTEP record and early rise at A&M were built in large part by playing incredibly weak OOC comp (his first A&M team went 19-9 regular season, 8-8 in the Big 12, and didn't make the tournament), and he inherited an All-American guard in Acie Law.
I think he was always a little bit crazy, but got a lot crazier at UK because he realized (probably right away) that it was too much, and he wasn't going to be able to handle it.
