Vontaze Burfict, Gerell Robinson and Omar Bolden headlined the participants at this year's Arizona State Pro Day held at Sun Devil Stadium Friday.

More than 40 NFL scouts and coaches were in attendance with notepads and stopwatches in hand, including Cincinnati head coach Marvin Lewis and Cardinals defensive coordinator Ray Horton.

Burfict, who has another Pro Day scheduled for March 30, was trying to bounce back from a disappointing showing at the NFL Scouting Combine in Indianapolis last month. Burfict unofficially put up 16 reps of 225 pounds on the bench press, which isn't a lot for a player of his size.

"It went average," Burfict said of his Friday performance. "I've got another one on the 30th, so that gives me 14 days, so I'll be in better shape. I thought I was in shape today, but I could be way more (in shape)."

Burfict weighed in at 249 pounds, after playing last season close to 260 pounds. The former Sun Devil said he'd like to get down to 245.

The usually media-shy Burfict was also asked about his performance in Indianapolis and admitted he could have worked harder to prepare.

"I blame myself, it was just immaturity. I'm growing up and realizing what the world is about and I've just got to work harder in everything I do," he said.

Robinson, who had a stellar senior season with 77 catches for nearly 1,400 yards and 7 touchdowns was pleased with his performance in Tempe.

"I caught everything and I feel like I looked pretty good in my routes and everything felt pretty clean, and if I faltered, I still finished up and made the play," he said.

Maybe the player on the turf at Frank Kush Field Friday with the most to prove, other than Burfict, is cornerback Omar Bolden, who missed most of the 2009 season and all of last year with knee injuries. Bolden proclaimed he has no issues with the knee as he prepares for the draft.

"I'm 100 percent healthy," he said. "I'm a little tight right now, but I'm 100 percent healthy."

Quarterback Brock Osweiler was in attendance, but didn't participate. He'll also take part in a Pro Day on March 30 and his workout will be supervised by former ASU offensive coordinator Noel Mazzone, who now holds the same post at UCLA.

Former Sun Devil Rudy Carpenter, who is currently on the roster of the NFL's Tampa Bay Buccaneers, threw to receivers and defensive backs.
