Coming out of college, O'Brien Schofield was regarded by many as a first-round talent, but his draft stock ultimately fell due to an ACL tear he suffered at the Senior Bowl. The pre-draft injury cost him at least a couple of million dollars, and a shot at being a day-one selection.
However, Arizona decided to take a chance on Schofield in the fourth round despite his injury. To start the season he was placed on the physically unable to perform list while his knee healed. After his time on the PUP was up, the Cardinals activated him for the final 10 games of the season.
He finished his rookie campaign with two sacks and six pressures total. The following season (2011) Schofield became a situational pass-rusher off the edge and logged 449 snaps. He upped his sack total to five while making a case for more playing time in Horton's defensive system.
His impressive sophomore season helped him grab a hold of the starting left outside linebacker position in 2012. He started the first nine games of the season and played 503 snaps before getting hurt during the Green Bay game. He was subsequently placed on injured reserve with ligament damage in his ankle.
It's unclear if Schofield will be given a chance to start in 2013. Rumors have it that the Cardinals may look to draft a pass-rusher on Day 1 or Day 2 of the draft.
