We don't know that to be absolute though either. How do you know RMK didn't tell him about the pinnacle of cbb at IU when they were at TT together? Maybe he always thought IU was a better job than Texas and that was a stepping stone.
We just don't know, but one thing we do know is he wants the job and would do well here!
I'm not saying he isn't a risk, but I would be willing to risk it for the reward he could reap.
