Those movie previews that give away too much of the plot?

That’s what it might feel like when the University of Hawaii basketball team opens training camp Saturday with an afternoon practice.

The Rainbow Warriors received an extended preview when they were granted 10 full practices this summer to prepare for a four-game Australian tour in August. The ’Bows worked on different personnel groups, gave extended minutes to newcomers and last year’s redshirts, and tested out a quicker-paced offense.

“How often can you have practices and games and travel together at that time of the year?” said Eran Ganot, who begins his fourth season as UH head coach. “I think our group is more acclimated to each other than most groups at this time of the year. But we’ve got to take advantage of that.”

The ’Bows were short-handed during the 1-3 tour. Zigmars Raimo, Justin Hemsley and Leland Green made the trip, but were not healthy enough to play. Raimo and Hemsley are now medically cleared, and Green should be fully healthy within a week.

The previous three seasons, Ganot has made alterations to the base four-out offense. This year, the addition of 7-foot, 240-pound Mate Colina and expanded roles of Jack Purchase, Samuta Avea and Hemsley provide flexibility for the ’Bows.

After graduating from Australia’s Lake Ginninderra High in December 2017, Colina opted to join the ’Bows in January instead of this summer. He redshirted during the spring semester.

“I took the opportunity to watch and learn,” Colina said.

Practicing with the ’Bows in the spring gave Colina “an advantage,” Ganot said.

Colina is a dual-skilled player who can protect the rim while possessing coast-to-coast stamina.

“I’ve said this earlier, he’s probably the best big man I’ve ever coached in terms of running the floor,” Ganot said. “He’s one of those guys who’s almost guaranteed to get better because of his work ethic and his approach and his desire to be good.”

Point guard Drew Buggs said Colina “runs the floor with the best of them. And he has great height.”

The ’Bows’ read-and-react offense often relies on creating shots off ball screens. But there is hope that two wing players — Avea, who has gained 10 pounds, and Hemsley, who was only 17 when he joined 14 months ago — can manufacture mismatches on post-up moves. Both also have worked extensively on their outside shots. “A lot of reps,” Avea said.

Hemsley said he spent several months testing several shooting styles before choosing a form that allows him to launch shots quickly, comfortably and confidently. “Having my shot be one motion and having a high arc works for me,” Hemsley said.

Purchase, who is 6-9 and 210 pounds, is a stretch 4 who attempted 74.5 percent of his shots from behind the arc the past season. He credited his shooting touch to an uncle, Andrew Gaze, an FIBA Hall of Fame member who is considered one of the best shooters in Australia basketball history. Gaze, the coach of the Sydney Kings, is on the island preparing his team to face the Los Angeles Clippers in a preseason exhibition at UH on Sunday.

“He taught me how to shoot,” Purchase said.

Purchase said he worked on his ball-handling and post moves during the offseason. “The more he can make plays off the bounce for our team, the better,” Ganot said.

There are no concerns about Purchase’s passing. “That’s just natural,” he said. “My dad (Nigel Purchase) was a good passer. I think that’s where I got it from. I just love watching good passes. That’s the best part of the game. I love getting assists. I almost prefer getting assists.”
