Iowa State inside linebacker A.J. Klein made his mark with four interception returns for touchdowns in his collegiate career, tying the FBS record for linebackers.
The 6'1", 250-pound senior might not wow anyone with speed or athleticism, but he makes up for it with instinct and intelligence.
Klein shared the 2011 Big 12 Defensive Player of the Year Award with Oklahoma defensive end Frank Alexander. He had 117 tackles, according to NFL.com, 7.5 tackles for loss, two sacks, an interception and six passes defended.
In 2012, Klein again made 117 tackles, 3.5 of them for loss, to go with his fourth career pick-six and was named to the Coaches All-Big 12 first team.
NFL Draft Scout labels Klein a "passionate defender" and also says he impressed at his pro day workout April 8 despite a sore right knee.
Klein was voted a team caption as a junior and senior.
