Ready or not, young ones, it’s time for college basketball.

Hawaii hopes an accelerated welcome to Division I hoops does not equal a rude one for some of its youngest players when it opens the 2013-14 season today against Tennessee State in the 49th Outrigger Hotels and Resorts Rainbow Classic.

Preseason injuries to guards Brandon Spearman and Quincy Smith mean some of the freshest Rainbow Warriors will get a chance to play immediately.

Spearman, a senior starter, is out an unknown length of time with a high right ankle sprain. Smith, UH’s backup point guard, is questionable for three Classic games through early Tuesday morning with lower back tightness.

Redshirt freshman Aaron Valdes and frosh Mike Thomas will get the bulk of Spearman’s minutes. Redshirt freshman Dyrbe Enos is the backup ballhandler.

This week, Valdes practiced in Spearman’s stead with first-teamers Keith Shamburger, Garrett Nevels, Isaac Fotu and Christian Standhardinger to prepare for a start in his first official game.

"I just have to be ready when Coach (Gib Arnold) calls me," said Valdes, who had eight points and 11 rebounds in UH’s exhibition win over BYU-Hawaii on Halloween. "It’ll be a good learning experience. Having four years to play, this is going to be big for me. We’re playing against good competition. But we’re just going to have to … make smart decisions out there. That’s what I hope to do and not turn the ball over."

Hawaii’s 19 turnovers were a bit of a concern in the exhibition. But that shouldn’t stop the ‘Bows from trying to play up-tempo behind its rebuilt backcourt and mobile bigs.

UH ended last season on a four-game slide en route to a 17-15 record. But the makeup and temperament of this year’s team is radically different. UH battled itself for a solid five weeks with a preseason expanded by a fortnight by the NCAA. Arnold said the extra time was "overall on the positive side" and he didn’t blame UH’s injuries on it.

"They’re definitely excited and have got a great competitive spirit," Arnold said of his players. "They’re ready to play, we’re ready to coach. It’s been a long preseason."

All four teams in this edition of the Rainbow Classic reached the postseason last year, making it easily the best field since the event went to a four-team round-robin format in 2009.

"We’re going to be tested real early. I think it’ll be good for us. We’ll see where we are," Arnold said.

For Shamburger, it’s been a long time coming. He’s played against UH for the past three years — the first two at San Jose State and last year as a scout-teamer while he redshirted.

"This is the big deal. We get a record now off these games," Shamburger said. "I’m going to go out there and give it my all no matter what the outcome is."

Tennessee State of the Ohio Valley Conference lost four starters from its CIT team of a year ago, but the sole starter that’s left must be respected. Point guard Patrick Miller is a returning first-team all-conference selection and has the green light at all times.

"He’s my coach on the court," Tigers coach Travis Williams said. "I’m expecting him to embrace that role. We’re young, have (nine) new guys. He’s gotta be that guy who makes us go."
