HONOLULU — When Chris Acker walks through the tunnels of the Stan Sheriff Center, he passes blown-up painted photos and plaques of Hawaii’s breakthrough Big West basketball championship season of 10 years ago. He sees his likeness on the wall.

“I feel chills because I know the sacrifices that were made when I was here,” Acker said Saturday night.

Eran Ganot’s ex-assistant siphoned a championship celebration from his old program as Long Beach State, led by precocious freshman guard Devin Sykes, played the role of spoiler to perfection in an 84-75 defeat of the Rainbow Warriors on their senior night.

It was not a fatal blow to the season, but an impactful one that laid bare divergent postseason paths for UH (22-8, 14-6 Big West). Suddenly, success or failure seem to hang on a razor’s edge in the Big West championships at Lee’s Family Forum in Henderson, Nev., even with UH already locking up a double bye into the semifinals.

UH knew rival UC Irvine had already locked up the No. 1 seed with an overtime win over UC Davis earlier in the day, but a share of a regular-season conference championship in the program’s final Big West season was there for the taking.

It would’ve been just the fourth regular-season title, shared or outright, in UH history and the first since Ganot’s first season of 2015-16. But UH subtmitted a listless performance.

“Twenty-three years (of coaching), I can remember almost every single game, the great moments, the tough moments,” Ganot said. “It’ll be there with us. It won’t own us, but it makes you who you are.”

Instead, UH heads into Henderson with a letdown that cast a melancholy spell over traditional postgame ceremonies for a senior class that injected new life into the program — Harry Rouhliadeff, Gytis Nemeiksa, Isaac Johnson, Dre Bullock, Hunter Erickson and Yacine Toumi.

As LBSU put the finishing touches on its victory, Ganot kneeled in front of the melancholy outgoing players and told them this one was on him.

“You want it so bad for them,” Ganot said after the team’s tribute video a few minutes later. “Even you see the emotions from the guys who weren’t seniors because they wanted so bad for them and for this group. that’s life sometimes didn’t happen our way Long Beach had a lot to do with that.

“We bounced back over the years, and this year, I expect us to again.”

Bullock, the high-flying wing who imbued the ‘Bows with some of their best individual highlights in years, had an emphatic two-handed baseline dunk in the first half among his 14 points, but he couldn’t find his outside shot. He was surprisingly subdued on his senior dunk with a polite deposit while draped in lei.

The four-year UH forward Rouhliadeff and the Utah State transfer Johnson were overcome by emotion during their senior introductions.

Rouhliadeff, of Brisbane, Australia, came out last to a lasting ovation from those who remained among the “white-out” crowd of 5,468 (6,512 tickets issued).

“It means the world to me,” Rouhliadeff said. “With all the time and effort I put into this place and for them to give me that standing ovation like I couldn’t help but come to tears. This place, this arena, it has holds a special place in my heart, and I will never forget that, and I will look back on all my time in Hawaii and cherish the moments that I have with my brothers and the coaches and the families that they have. They’re the best people in the world, and I honestly, I can’t thank them enough bringing me here.”

Like many on the rebuilt roster, Johnson has been at UH less than a full calendar year but the Utah native said he has been impacted nonetheless. The “Big Fish,” who got the UH faithful to buy into his signature arm chomp celebration almost immediately upon arrival, teared up as he flashed double shakas to the crowd.

“I feel like you’re not a true man if you can’t show a little emotion,” Johnson said. “And I couldn’t hold it back.”

As for reconciling those feelings with the frustration of the in which he registered 16 points and eight rebounds, he said “It’s a basketball game. There’s a lot more in life than basketball. Bummed we lost that one. We got to go get a ring the hard way.”

UH remains the No. 2 seed in the eight-team tournament and will play in the late game Friday (8:30 p.m. Pacific/5:30 p.m. Hawaii time) against one of No. 6 seed UC Davis, No. 7 UC Santa Barbara or No. 3 Cal State Fullerton.

Long Beach State (10-22, 6-14) bought into metaphorical championship stakes that proved potent enough to contend with UH’s actual championship opportunity: End your season with a memorable win that will be a building block for future success, the second-year leader Acker told them.

Sykes, the Big West’s second-leading scorer who missed the teams’ first meeting Jan. 31 at the Pyramid, answered the call by splashing 3-pointers on three straight possessions to turn a tight game into a runaway. Sykes scored 34, a season high for a UH opponent.

Sykes said he was motivated to send LBSU’s seniors out on a victory. Some of his pulls nearly touched the edges of the center court “H.”

“I actually was shooting the exact same shots in warm-ups on the logo, and that’s exactly what I remembered,” Sykes said. “I was like, ‘I’m just gonna shoot it, and I think it’s going to go in’ and it did.”

UH learned it was in for a battle after it took a quick lead. LBSU built a double-digit lead at the half. When UH claimed a 58-55 lead with 11 minutes left, the Beach response was swift.

Erickson, who scored 18 of his season-high 23 points in the first half, said he thought the team overreacted to the Beach hitting tough shots. LBSU shot 50% (9-for-18) on 3s.

The Utah transfer, one of a few married players on one of the oldest teams in college basketball, said he and his wife now consider Hawaii a second home.

“Obviously it didn’t turn out how we wanted in the game, but we got everything we want ahead of us still,” Erickson said. “We got the Big West championship coming up, and, you know, fighting for that championship to get to the NCAA tournament.

“That’s the biggest goal, and that’s the goal I came to achieve.”

Ganot was assessed a rare technical foul with under five minutes to play and UH trailing by five when Rouhliadeff hit the deck for a loose ball. Ganot attempted to call timeout (or get one of his players to) and grasped a nearby official on the floor as he called out.

The referee told him the technical was for where he was positioned on the floor.

“I gotta own it,” Ganot said. “(I’m) not a guy who’s very demonstrative as a coach in this league or in the country, and disappointed that happened, but that was a communication to me that I was on the floor.”

It figures to be an impactful week to come as Ganot is still on the final year of his contract. However, should UH fall short of winning the tournament and gaining the automatic NCAA Tournament berth, the NIT is a possibility given UH’s top-125 NET and KenPom ratings.

In the handshake line, Ganot told Acker and his other former assistant John Montgomery they deserved the win in their last Big West appearance in the building.

Acker lauded Ganot for his nine years since Acker left to assist at Boise State, San Diego State and head up LBSU.

“I know what Eran’s about and what his program’s about and what he’s trying to build, and what he has built here,” Acker said. “So it’s always special to come in here, play and compete and to see Rich (arena manager Sheriff) and to see all you guys here. It’s ohana.”

“I told the guys before the game, what we did in my tenure here was special,” Acker said. “And there’s a legacy on the wall for all the players and coaches who were here during that time. … I know what Eran’s about and what his program’s about and what he’s trying to build, and what he has built here.”
