If TJ's done nothing but lose at UNLV, then don't hire him. I don't know his exact record there and honestly am not interested enough to look it up.
John Beilein has won consistently at the college level. He has 27 seasons in Division 1 NCAA and an overall winning record as a coach. He's had a winning record at every stop in the NCAA. One year of terrible results in the NBA is a fluke, showing he's just not good at the NBA level. He's had only 4 seasons below .500 in the NCAA, having winning seasons in 85% of the years he's coached D1 NCAA. He's never had back to back losing seasons in his career. I'm not saying hire Beilein, but I'd be open to hiring him. His track record is entirely different than Hoiberg's.
Hoiberg has coached 2 consecutive seasons of losing basketball in the NCAA, and 2 consecutive losing seasons in the NBA before that. But throw out the NBA. In the NCAA he's got a track record of having winning seasons 4 out of 7 years, only about 57% of the time. Losing is becoming a pattern for Hoiberg. He can still break out of it, but imo it's not justified for us to take a chance on a coach who is on a downward trend.
Taking over at West Virginia and Michigan might be slightly different than Iowa State and Nebraska.
