LOS ANGELES — Sometimes less is not more.

In the case of Florida State, more is more.

The Seminoles, with a roster deeper than our country’s national debt, sends so many different players onto the court, it’s difficult for the opposition to keep track of who’s in the game at any given time.

Most teams in the NCAA Tournament shrink their bench to increase minutes for their best players.

Not Florida State coach Leonard Hamilton. He always likes to beat teams with numbers — a lot of numbers.

In Thursday night’s West Region semifinal at Staples Center, Hamilton’s ninth-seeded Seminoles, aided by their unrelenting depth, upset fourth-seeded Gonzaga, 75-60, to advance to Saturday’s regional final against Michigan, which crushed Texas A&M earlier in the night.

“We win games by committee,’’ Hamilton said afterward.

“We come at you wave after wave, and it really hurt teams,’’ Seminoles forward Phil Cofer said.

“It’s definitely our goal to try to wear people down with our depth,’’ Florida State reserve Brandon Allen said. “It can be difficult, because we have a lot of talented players that have to take a back seat sometimes. That can be a challenge for guys mentally to stay engaged.’’

Allen represents the poster child for what Hamilton calls his “18 strong’’ team.

It was Allen’s basket at the halftime buzzer that gave Florida State a nine-point lead at the intermission, put an exclamation point on an 11-1 Seminoles’ run and energized his team for the second half.

“It’s always a momentum change when you hit a shot at the buzzer,” Allen said, “but I think the team was energized by the fact that I made the shot, because I don’t get to play a lot [he played two minutes Thursday night] and I came in and made an impact and the team was happy for me.’’

Florida State will make its third Elite Eight appearance in school history, but the first since 1993.

Thursday marked the third consecutive game in which the Seminoles (23-11) defeated a higher-seeded team.

Just four days earlier, they upset No. 1 seed Xavier with a furious 18-4 rally in the final minutes.

So, any thoughts that Florida State is a football-only school should be tabled for the moment.

Gonzaga (32-5), the quintessential basketball school, was playing in its fourth consecutive Sweet 16 and trying to advance to the Elite Eight for the third time in four years. The Zags, who lost in last year’s title game to North Carolina, again fell bitterly short of the desperate goal of winning their first national championship.

Credit gritty Florida State’s wear-you-down depth for that. The Seminoles have 10 players who average at least 10 minutes per game. They have nine players who average at least 6.6 points per game.

Of the 11 Florida State players who scored against Gonzaga, only Terance Mann reached double figures, with 18 points. Just six players scored for Gonzaga, which was led by Rui Hachimura’s 16 points and Zach Norvell Jr.’s 14.

“It shows how balanced we are,’’ Mann said. “Even though I was the only double-digit scorer, there were a lot of nines and eights and fives in there. We’re a deep team. Any given guy can step up. I mean, I can’t remember the last time I was the leading scorer in a game.

“It can be any of us. Our walk-on [Allen] came in and hit a big floater at the end of the first half.’’

This was an issue that concerned Gonzaga coach Mark Few before the game.

“Usually you have seven or eight guys to deal with, but not 11,’’ Few said. “It’s impressive that they’ve been able to play that many. Usually what you see in college basketball is a tendency to kind of shrink your bench as you get farther along and deeper in the season and into the postseason.’’

When Hamilton was asked on Wednesday if he ever thought of shortening his bench in an effort to get more minutes for his better players, he said matter-of-factly: “No, I have not. I don’t think that’s who we are. We’re 18 strong.’’
