The Des Moines native impressed across the board in the March 19 workout. His 4.44-second 40 and 41-inch vertical leap proved particularly noteworthy.
"I PR'd (personal record) in a few of those drills, but I knew I could put up those numbers," Bernstine said.

When a prospect creates a name for himself later in the process, many teams want to protect their thoughts on him. They play their cards close to the vest to keep the opposition guessing as to where they might select him.
Bernstine has worked out for several teams.
"I really don't talk about the teams," Bernstine said with a smile. " I've been talking to a few teams, me and my agent, and going through the whole process."
A series of injuries during his Hawkeye career could have led pro scouts to lose track of Bernstine. He entered the Iowa program as Scout.com four-star recruit, the service's No. 29 safety nationally in his class.
"It was difficult to a point just because I had a few injuries here and there," Bernstine said. "It was more timing than anything else, like fall camp, when I was competing for a position. The guys that went in took it and ran with it. We have Amari Spievey. We have Shaun Prater. They're both good guys.
"It's been a hard process, but I just stuck in there, worked hard and tried to have a good senior season."
Bernstine ranked seventh in the Big Ten in kickoff returns (23.8 YPR) and 10th in tackles (7.4) as Iowa's strong safety in 2011. He's played both safety positions and corner at Iowa.
"I think that's a big selling point, what teams like about me is my versatility," Bernstine said. "I can play all of the positions in the secondary as well as help out on special teams."
