Buffalo has been called a Cinderella after knocking off No. 4 seed Arizona in the opening round of the South Region.

The 13th-seeded Bulls don't like the tag at all.

"Everybody thinks we should be here and yesterday's game wasn't a fluke or whatever you call it," said Bulls guard Jeremy Harris, who made a face when asked about Cinderellas in the NCAA Tournament. "I think we are a very confident team and I don't really like the term 'Cinderella team.'"

Buffalo set a school record for wins this season and won the Mid-American Conference Tournament title after clinching the East Division title by three games during the regular season.

The Bulls started down a national power in its opening-round NCAA Tournament game and got Arizona to blink, racing away from the Wildcats in an 89-68, bracket-busting victory. Buffalo hit 15 3-pointers to win its first NCAA Tournament game and earn a spot in the round of 32 against another powerhouse program, Kentucky.

 "We're a team that plays very hard," said Harris, who had 23 points against Arizona. "We've got some tough guards ... we give each other confidence all game."
