The Gonzaga Bulldogs, aka the “Zags,” are seeking admission into one of college basketball’s most revered fraternities—The Undefeated Club.

There have only been seven undefeated NCAA Division I basketball champions and four have the same initials, “UCLA.”

The UCLA Bruins enjoyed four perfect seasons while the University of San Francisco, the University of North Carolina and Indiana University recorded one each, all long ago.

There hasn’t been an undefeated team since Indiana in 1976, when President Gerald Ford was in the White House, “Rocky” was premiering on the silver screen and Bob McAdoo was leading the NBA in scoring for the Buffalo Braves.

A private Catholic university in Spokane, Wash., Gonzaga improved to 28-0 Tuesday by eliminating Oklahoma 87-71 in the second round of the NCAA Tournament in the West Region in Indianapolis.

Coach Mark Few’s squad features two likely NBA first round picks in senior Corey Kispert and freshman Jalen Suggs.

Prior to dominating the West Coast Conference, Gonzaga scored early season wins over heavyweights Kan- sas, Auburn, West Virginia, Iowa and Virginia. That enabled Gonzaga to surge to the top of the polls. The Few Crew never let up on the gas, averaging 92 points per game.

Named after Jesuit saint Aloysius Gonzaga, the school needs four more wins to ring the loudest bell in the NCAA’s tallest tower.
