Mark Few helped transform Gonzaga from a little-known school in the Pacific Northwest into a national powerhouse.

The Zags have dominated the West Coast Conference in Few's 19 seasons as head coach and has the nation's fourth-longest NCAA Tournament streak at 20 straight years.

Gonzaga (31-4) reached its first Final Four last season, losing to North Carolina in the title game, and beat UNC-Greensboro to win its 10th straight opening-round NCAA Tournament game, matching Kansas for longest in the country.

But for all the hard work it took to get the Zags on top, keeping them there has been more difficult in their coach's eyes.

"Just speaking from experience, I'd say it's a lot hard to maintain a high level of success," Few said. "That's why I have so much respect for Coach Cal (John Calipari), Duke and North Carolina, just to be able to stay at that level because it's a constant pecking away at you in every way, shape and form. And it's everybody's biggest game.

"We've done both. We've built our program up and were the Cinderella for a while. The maintainance part is a lot hard than I think people realize."

Gonzaga faces Ohio State in the round of 32.
