Yes, you can certainly criticize his departure but he did a fantastic job of coaching at Texas Tech. A Sweet 16 appearance, as well as improving from 8 wins the year before he arrived to 23 his first year in Lubbock was remarkable.
Actually he pretty much destroyed Tech basketball, leaving it worse off than when he started. He won early with Dickey’s recruits but his teams got progressively worse because he put no effort into recruiting and ran off the few good players we did get. He had no interest in that program except for what he could get out of it. Good X’s and O’s coach but a despicable human being
