OK, Llama's time is up. My selection is:
Greg Popovich, Coach, Spurs
Daly was goig to be my choice until he got nabbed. In my mind there just isn't a better lock-down defensive type coach available. Also, three championships in seven years puts Pop in the conversation with Riley. He hasn't won 6 in eight years, or three in a row like Auerbach or Jackson, but I think Popovich would obtain similar results if he had Jordan or those Celtic teams.
Besides, I think Pop probably has a few more championships coming in the next few years.
