Mother Nature brought the rain, the University of Hawaii football team delivered the heat.

In Saturday’s spring practice that had a little bit of this and a lot of that, the Rainbow Warriors made big plays on both sides in four scrimmage-like sessions spanning about 75 minutes.

From the opening period’s “Oklahoma drill” — a 3-on-3 battle on a narrow 10-yard patch — “we just played all out,” middle linebacker Jahlani Tavai said.

This was the 12th of 15 practices in a spring training that concludes with Friday’s controlled scrimmage. “It was kind of like a sneak peek,” said Aaron Zwahlen, who is in a three-quarterback competition for the starting job.

The Warriors went to the long menu during the 79 scrimmage-like plays. In the red-zone drill, U-back Kaiwi Chung did football’s version of a pick-and-roll, setting a brush-block stance, then curling to the flats to catch Beau Reilly’s 7-yard scoring pass.

“I haven’t played basketball since KAC,” said Chung, a former Kamehameha offensive lineman who converted to U-back this spring.

Tight end Metuisela Unga, like Chung, is a skilled blocker who also has to work extensively on his catching. Unga’s 3-yard scoring reception from Zwahlen came a session after he was knocked down by middle linebacker Solomon Matautia.

“That’s part of the game,” Unga said. “Sometimes you’re going to get hit in a way you don’t like, but you just have to get back up.”

The defense also had other mouthpiece-loosening hits. Nose tackle Kiko Faalologo stuffed running back Ryan Tuiasoa for a 2-yard loss and a safety. Zeno Choi, a walk-on who can play both defensive-tackle positions, had a sack and another backfield tackle.

“Zeno is Mr. Reliable,” defensive line coach Legi Suiaunoa said. “He’s never missed a practice. He’s never been banged up. He’s gotten better throughout spring camp.”

Malachi Mageo, who was promoted following strongside linebacker Dany Mulanga’s injury, made two interceptions in consecutive series. On the second, the ball fluttered when defensive end Meffy Koloamatangi hit the quarterback. “It was just a floater, and I happened to be there,” Mageo said.

But the offense also had its moments. Running back Paul Harris scooted 66 yards for a touchdown.

“I was patient, I followed my blocks, and then a hole opened,” Harris said.

And left wideout Marcus Kemp, who has fully healed from a knee injury, went 73 yards on a catch-and-dash scoring play. Kemp ran a slant on a rocket screen, then caught the pass from Ikaika Woolsey. “I spun around, and took off,” Kemp said.

“He hit the ‘B’ button,” said wideout Andrew James-Ho, referring to a video game’s spin control.

Kemp barely out-raced safety Dejaun Butler to the goal line.

“I knew if I got caught, I’d be feeling it in the meeting room,” Kemp said. “I tried to put on the extra gas so he wouldn’t catch me.”

Butler said: “He’s faster than he looks. He has those long strides. He’s got some speed. It was a good play by our offense. Everybody is coming out here and competing, and I like it.”
