To me it looks like he was dead set on moving on from Harper, point blank period. He knew he needed a new coach and probably put feelers out and saw that his pool wouldn’t be that large. He made his best educated guess on who was left would be the most successful.
I think to hire an established coach, an AD has to have good relationships with various agents and probably some established coaches around the country. And you have to have the rocks to go for it--go for it in terms of pitching the program (which doesn't need pitching) and the opportunity, and be ready to spend money. Ask yourself if White would do this for the men's program. If he did, there'd be the same uproar, because nobody does it.
Sometimes, for sure, you can hit it with a hire like this--we did with Bruce Pearl on the men's side. But this: Pearl had been an assistant coach at both Stanford and Iowa, then was a mid-major head coach for 14 years (Southern Indiana and Milwaukee) before UT hired him. Big difference.
