Gonzaga, the top No. 1 seed, is the first team to enter the N.C.A.A. men’s tournament undefeated since Kentucky in 2014-15, and the Zags have a legitimate shot to become the first undefeated national champion since Indiana finished 32-0 in the 1975-76 season.
Gonzaga is 26-0 after beating Brigham Young to win the West Coast Conference championship on Tuesday. The Zags have a free-flowing, fast-paced offense, and they pass up the good shot for the great shot. But while Gonzaga has wins over Kansas, West Virginia, Iowa and Virginia, it has not faced an opponent outside the West Coast Conference since December.
