Few himself has tempered expectations every year even with his best teams. To win it all requires not just great talent but a bit of luck. Look at Virginia -- that game could have gone either way if, noting to do with the coach or the players.
Not sure if you live in the Spokane area or not, but the love affair with the Zags will keep going on as long as the current culture stays in place, regardless of Final 4 victories.
