After 15 practices over five weeks, the Hawaii football team exited spring training without a No. 1 quarterback.

“That’s not a real good situation to be in,” said Norm Chow, the Warriors’ first-year head coach. “I don’t like doing that.”

Chow had hoped to decide between David Graves, who started two games last year, and Jeremy Higgins, who redshirted in 2011 after transferring from Utah State.

“We’re not ready to make that decision yet,” Chow said.

Graves entered spring training as the No. 1 quarterback, He admittedly has been inconsistent in the transition from last year’s four-wide passing attack to Chow’s pro-set offense.

Graves has been given leeway for not completing passes. But Chow has expressed frustration with Graves’ decision to abandon the designed play too early. Chow noted Graves might not spot an open receiver if he is scrambling.

Higgins, a 2010 Saint Louis School graduate, was the No. 4 quarterback at the start of spring training. He moved up a spot when Cayman Shutter was suspended indefinitely, then vaulted past freshman Ikaika Woolsey.

Higgins has played well in the past two scrimmages. He was 5-for-9 for 135 yards and two touchdowns on Maui on April 21, and 10-for-23 for 100 yards in the Warrior Bowl on Friday.

“Somebody is going to have to take the first snap” in training camp in August, Chow said. “We have some time to figure it out.”

There also is uncertainty at the two receiver positions. Billy Ray Stutzmann and Chris Gant were the No. 1 receivers following the Maui scrimmage. Stutzmann did not play in the Warrior Bowl because of a sore knee and Gant struggled, catching two of six passes thrown in his direction.

Chow said Trevor Davis, Miah Ostrowski, Scott Harding, Allen Sampson, Justin Clapp and Cecil Doe are in the mix at receiver. Ostrowski, who is 5-9, was a slotback last year.

“Everyone assumes he’s an inside (receiver), but why can’t he play outside?” Chow said. “Ostrowski has been doing a lot of good things. We have a lot to choose from. Nothing is set in stone at the wide receiver spots. Nothing at all.”

Chow’s base offense uses a fullback. Dustin Elisara suffered a serious knee injury on Maui, and Jared Leaf has missed half of spring training because of an illness. Chow said Justin Vele, a converted linebacker, has been doing well at fullback. Ethan Watanabe, who joins the Warriors this summer, will compete at fullback. Chow said a fullback will be used between 15 and 20 times a game.

“If we don’t have the right fullback, we won’t use a fullback,” Chow said. “We’re committed to making sure we do what’s right for our kids.”

Chow said UH has the option of using two running backs in the same backfield. Joey Iosefa, John Lister and Will Gregory have rotated at running back. Samson Anguay and Sterling Jackson are recovering from injuries but should be ready for training camp.

“When you think we installed a whole new offense, defense and special teams, I thought the players responded well,” Chow said. “They bought in. (Ohio State coach) Urban Meyer always said: It’s 1 percent scheme and the rest buying in. The guys bought in.”

Here’s a tentative list of the No. 1 players:

OFFENSE:

Left tackle Blake Muir, left guard Ben Dew, center Ben Clarke, right guard David Lefotu, right tackle Jordan Loeffler, tight end Craig Cofer, fullback Justin Vele, running back Joey Iosefa.
