Heard Lute Olson took a leave of absence. Whats up with that?

Well, since there ain't sheet happening in town, that has been in all the news lately. Nobody is coming out and saying what is up, but there is alot of speculation. He claims it isn't health related, but a private matter, so take that how you want. I really don't know, or even care that much, but you can imagine how big the story has been...
