Having by no means missed a game, he holds the school record with 54 career starts. Castonzo gave up only 1 sack this past season and missed seven assignments. He had 40 knockdowns and consistently graded out as the highest on the offensive line. He had only two penalties in 820 plays. He was also nominated for a Rhodes Scholarship, and will soon graduate having a degree in biochemistry. His plans to conduct cancer research are on hold, although, simply because he was the 22nd overall pick in the NFL draft.Spring replacement: John WetzelTheres just no method to account for the loss of 54 career starts, but Wetzel had a great sufficient spring to earn the top spot on the post-spring depth chart.
