This lady would have been fired a few years back for my money. It was obvious she wasn't one of the elite coaches and very quickly Tennessee quickly dropped below elite status early on in her tenure. And that is what she signed up for at that place.
I know I've said it a thousand times, history doesn't matter, neither does money, reputation, the color of the uniform, or the number of trophies in the case, or even the quality of player that keeps coming in. If you don't have an elite coach you aren't going anywhere. Coaching is everything.
