INDIANAPOLIS — For four University of Hawai'i pro-football prospects, good results in the 50 is nearly as important as ones in the 40.

Yesterday at the National Football League Scouting Combine, quarterback Colt Brennan and receivers Jason Rivers, Davone Bess and Ryan Grice-Mullins took the Wonderlic, a 50-question quiz that measures personality and intelligence. There was a time limit of 12 minutes.

"It was intense," Bess said.

Each answered at least 30 questions, which is considered to be a good amount considering the time restrictions.

Brennan said he felt he did well. "But you never really know because they don't give you any feedback," he said.

"It was OK," Rivers said.

Rivers and Brennan did not participate in the weight-lifting sessions. Rivers said he will lift during the April 1 Pro Day in Carson, Calif.

Brennan said he wanted to focus on today's passing drills. He said he was told quarterbacks are not judged on sprints or weight-lifting.

"It's on-field decisions that matter the most," Brennan said.

Grice-Mullins bench pressed 225 pounds 17 times.

"I'm kind of disappointed with that," he said. "I think I could have done more."

Bess had 14 repetitions, but said one of his lifts was disallowed.

"Put it down at 14," he said.

He said he had not had more than nine repetitions until he started training in Arizona last month.

"I'm stronger and more confident," he said.

The receivers face a key workout today in the 40-yard dash, what has become the standard measurement for speed.

Rivers, who has run the 40 in 4.45 seconds, hopes to run in the low 4.4s. If he can break 4.4, he might elevate into a first-day prospect. The first two rounds of the NFL draft will be held April 26; the final five April 27.

Rivers said he will wear Nike Mercurial Vapor cleats. Each shoe weighs about 6 ounces.

"They're light as a feather," agent Leo Goeas said.

Grice-Mullins and Bess also chose light cleats. The RCA Dome has the same type of FieldTurf as Aloha Stadium.

"The knock right now is my top-end speed," Bess said. "I have to show them I can run."

Bess said he had past problems with his start. He believed he was ascending from his stance too quickly.

"The key is to start low and drive through," Bess said.

He said better technique might shave a tenth of a second. His goal is to run the 40 in under 4.6 seconds.

Bess and Brennan have been asked to participate in individual workouts for NFL teams.

Bess said he has spoken with the Cincinnati Bengals and Denver Broncos. The Bengals are seeking an inside receiver who can return kicks.

"I'm here," Bess told a Cincinnati reporter. "I'm on the market."
