I actually consider him one of the greatest coaches of all-time. He literally built a program in the desert and unlike UNLV, Tucson is FAR from a destination vacation. Having been there (3 years ago) I can say Tucson is the semi successful place it is today thanks to Lute Olsen. Without him being there, Tucson (and the University of Arizona) is community school level.
Unlike Jim Calhoun (who I have an unhealthy dislike for), Lute did not have the fertile talent pool to build from. Their stories are similar in regards to building a national program though.
He lived a long time... and his contributions to the school, city, and state will be remembered for the next 100 years. RIP Coach.
