Two-tenths of a second is enough time to form a first impression of a Web site but not enough for a catch-and-shoot play in the NBA.

For former University of Hawaii running back Joey Iosefa, two-tenths of a second is needed to erase a first impression and, perhaps, catch the attention of pro-football scouts.

"Time to redeem myself," said Iosefa, who will compete in UH’s pro day in San Diego on Thursday.

In last month’s NFL scouting combine in Indianapolis, Iosefa completed the 40-yard dash in 5.02 seconds. It was the slowest 40 time among the 30 running backs at the combine.

There were two things to consider. Iosefa, who is 6 feet and weighed 247 pounds that day, was grouped out of position. Iosefa is a big back whose skills are suited for lead blocking, pass routes into the flat, or getting the ball in third-down or short-yardage situations. At the combine, he led all backs by bench pressing 225 pounds 30 times.

The other thing is Iosefa probably should not have run that day. After the 2014 season, the agenda was for Iosefa to strengthen his ankles and feet — ailing areas during his UH career — and prepare for pro day. But Iosefa received the NFL invitation two weeks ahead of the combine.

"You can’t go to the combine being an underdog and say you’re not going to run the 40," said Chad Ikei, Iosefa’s trainer.

After the combine, Iosefa resumed training in Honolulu. He sliced body fat, and he weighed 241 pounds when he left Honolulu on Monday — smack in the middle of the goal range of 240 to 242 pounds. He weighed 262 at the end of the season.

Iosefa has worked on his sprint technique and form. In the combine, Ikei suggested, Iosefa "tensed up" at the starting line, and then shortened his strides.

"He needs to be relaxed," Ikei said.

In trial sprints, Iosefa clocked 4.80, although that was discounted because it was severely wind-aided. He also ran 4.87 and 4.91.

"Joey is not a blazer," Ikei said. "I believe he can run in the 4.8 range. If he runs under, that’s even better. As long as he can run 4.9 or better."

Former Rainbow Warrior Scott Harding is another intriguing prospect.

Harding, who was used as a punter and punt returner at UH, will compete as a slotback at pro day.

Harding was grouped with the wide receivers during an NFL regional combine in Chicago two weeks ago. Harding rotated between wideout and slotback as a junior, before moving inside exclusively last season.

At the regional, Harding ran the 40 in 4.6 seconds and, by most accounts, was crisp with his routes. He caught all six passes in his direction; two were badly overthrown.

Former UH center Kody Afusia lost 14 pounds and now weighs 304. He has worked on hip flexibility and "explosion" during his eight weeks training in Irvine. His daily schedule: strength/conditioning workouts from 8 a.m. to 1:30 p.m., position work for an hour, then cardio drills in the late afternoon.

Twice a week, Afusia meets with Jesse Sapolu, a former UH center who won four Super Bowl rings with the San Francisco 49ers.

For former UH defensive end Beau Yap, the key measurement will be his reach and wing span. Yap, who is 6 feet 2 and 245 pounds, projects as a rush end or outside linebacker. Yap has the speed (sub-4.8 in the 40) and motor. He hopes to display those skills during the afternoon position drills.

There are 17 former Warriors competing at pro day, including linebacker Art Laurel and quarterback Cayman Shutter. Laurel, who finished his UH career in 2013, missed last year’s pro day while recovering from shoulder surgery. Shutter’s UH career ended in 2012. He spent the past two years playing for a university in Canada.
