|Despite lacking the ideal size and desirable speed usually possessed by college football's elite inside linebackers, Klein was a consistent force for three seasons at Iowa State. The Cyclones' leading tackler as a junior and senior, Klein was the Big 12 co-defensive player of the year in 2011 when he made 116 tackles and recorded two sacks. As a senior, he made 117 tackles to again earn all-Big 12 first-team honors for a squad that finished 6-7. His four career interceptions returned for touchdowns ties for the most among FBS linebackers. Though Klein does not have top-notch pursuit or recovery speed, he's intelligent enough to play both inside or out, though inside is likely where he'll make his money. If he's able to fine-tune some things and continue to impress with his work ethic, Klein has the instinct and overall talent to be a three-down NFL player. He did not stand out at the combine, where a knee problem kept him from participating in the shuttle run and vertical jump. However, that likely won't deter him from being a mid-round selection with the potential to contribute immediately on special teams. Klein has drawn comparisons to New Orleans' Scott Shanle.
