Maybe Baylor can give Gonzaga a game. UCLA, coming off upsets of Alabama and Michigan, could offer some resistance.

Miracles do happen. It’s called March Madness for a reason.

But USC was supposed to provide a test for the Zags, its length and firepower serving as at least an impediment. Gonzaga laughed at the mere suggestion. It scoffed at the notion. It treated the sixth seed in the West Region like a punching bag that didn’t deserve to share the same court. It overwhelmed Evan Mobley, the Trojans’ elite NBA prospect who could wind up as the first pick in July’s draft.

Mark Few’s undefeated team took another step toward becoming the first group to go wire-to-wire without a loss in 45 years Tuesday night, eviscerating USC, 85-66, at Lucas Oil Stadium in Indianapolis. Gonzaga is the first program to reach the Final Four without a defeat since Kentucky in 2015, and the first team to advance to the sport’s biggest stage by winning its first four tournament games by double figures since Villanova in 2018. It has defeated its four opponents by a combined 95 points, making a mockery of the tournament known so far for upsets.

“It’s hard not to think about it,” prized freshman guard Jalen Suggs said. “It’s a great accomplishment to be mentioned with those teams because they’re amazing.”

So is Gonzaga (30-0). The Bulldogs’ passing was brilliant. Their shotmaking was typically on target. They shredded the USC (25-8) zone that had been so effective through the first three rounds, registering 21 assists on 33 made field-goal attempts, and didn’t have a single shot blocked by the nation’s top shot-blocking team.

“We were really moving in unison,” said Suggs, the projected top-three draft pick who had a near triple-double with 18 points, 10 rebounds and eight assists.

Perhaps just as impressive, their defense — the aspect of this team that gets overlooked — was better than advertised. Gonzaga held USC to 38 percent shooting and just four made 3-pointers, swarming the Trojans and frequently turning defense into offense.

The Mobley brothers, Evan and Isaiah, had no answer for Gonzaga’s Drew Timme, the best big man on the floor. He not only scored 23 points, but also had four assists and three steals. In the game’s opening minute, Timme produced two USC turnovers, a fitting start for the action that followed.

“It set the tone that, ‘Hey, we’re going to be aggressive,’ ” Few said.

The game was over early. Gonzaga led 17-4 just 5:32 in. It was 29-12 at one point and a 19-point difference at the half. The Zags put up 49 first-half points, the most allowed by USC in a half this season. The previous high was 36.

At the buzzer, Gonzaga celebrated its accomplishment, despite how inevitable it felt most of the evening and how dominant this season has been. That was important to Few. This was only the second time the Zags have reached the Final Four in 23 trips to the tournament.

“This is something that needs to be celebrated, and we need to take the time to enjoy the heck out of it,” the Gonzaga coach said, “because I think you’re just missing the whole point in life if all you’re doing is going to the very end game and that’s the only way you’re going to celebrate and feel good about anything.”

Of course, Few noted, the job isn’t finished. The ultimate goal hasn’t been reached. Don’t think his players or coaching staff are anywhere close to satisfied. They’re two wins from really making history.

“These steps get harder and harder, and the next one’s going to be really hard,” Few said.

Official Bert Smith collapsed and hit his head on the floor during the first half of the game, halting play for several minutes. He was taken off on a stretcher and appeared to be alert. The NCAA announced in a statement that he was suffering from an undefined “medical issue,” but was stable and was not being transported to a hospital. Rules analyst Gene Steratore said on the TBS broadcast Smith was feeling light-headed in the locker room.
