Here's a more detailed press release about the hire:

It almost seems that the Jazz went to a flea market and hired the cheapest temporary coach they could find to help the rooks and sophs develop during a shortened season. The dude can't seem to stay at one place for more than a couple of years. How long will he stay with the Jazz? Now granted the guy is like 51 years old, so he may just retire with the Jazz, but why could he not stay at one place?
Also, he's not a center or a power forward or anything. Yet he will be teaching the bigs how to play? Well I'll give him the benefit of the doubt, you don't have to be good at something to teach someone else, just look at Scott Layden, I'm pretty sure he hasn't played any basketball of note, yet he's been an NBA exec/coach for years.
My end analyses is that he will be helpful to have around to help the young players develop, and he has plenty of experience in plenty of systems. Not worried about it.
