Cornerback Jamar Taylor ran the 40-yard dash in 4.33 seconds in Boise State's spring testing two years ago.

He matched that time - exactly - last year.

So he's confident going into the NFL Scouting Combine in Indianapolis, where he will run the always-important 40 on Tuesday.

Taylor's goal: a time faster than 4.4 seconds, which has been accomplished by just four cornerbacks in the past three combines.

"I feel like I'm a 4.3 guy," he said. "I ran it two years consistently at Boise, so I figure what's the difference here?"

Taylor and tailback D.J. Harper are Boise State's two combine invitees this year.

Harper is scheduled to perform the bench press Saturday and on-field tests, including the 40, on Sunday. Taylor lifts Monday and runs Tuesday.

NFL Network and NFL.com will provide live coverage of the on-field testing beginning at 7 a.m. Saturday-Tuesday. The running backs run the 40 at 11 a.m. Sunday, and the cornerbacks at 7 a.m. Tuesday.

The players' four-day itinerary also includes medical testing - that will be key for Harper, who tore his left anterior cruciate ligament in 2009 and 2010 - and meetings with NFL scouts, coaches and other personnel evaluators.

Taylor got a preview at the Senior Bowl.

"I feel like I just need to be myself and not be somebody I'm not," he said. "I'm not a crazy person. I'm not somebody who is overly cocky. Just be myself and just answer the questions."

Taylor is considered a potential second- or third-round draft pick. NFL.com rates him as the No. 7 cornerback in the draft.

He helped himself at the Senior Bowl despite missing the game with an illness.

"I feel like I still did what I wanted to do during the week," he said. "I wanted to play in the game because I wanted to compete with the South team, but I had to take it and roll with it."

He gets another chance to impress Tuesday - and that 4-second run could have a major impact on his draft stock.

"Of course you want to do good in everything," Taylor said. "But really, that's what everybody cares about. You can do good in everything else but if you run a slow 40, that can kill you."
