make a run to the tournament and compete for a conference title in that year and then in the subsequent years do you really think he'd leave what he built for crappy Fresno. It was a not a parallel move, that is a step down.
He saw the writing on the wall and took another job before BYU would fire him. He's no dummy and he found himself another job.
would he have been canned after that season - maybe maybe not but it was most definitely a possibility and he knew it. Have you forgotten how bad his last two years were? It was fire-able bad.
IMO, he figured he was going to be fired and made other arrangements.
