Most players who go to prep school need academic improvement. Not Castonzo, who scored 35 out of a possible 36 on the ACT in high school in Illinois. But the only schools interested in Castonzo out of high school were Princeton, Yale and Holy Cross. Castonzo thought he could be an FBS player, so he went to Fork Union Military Academy for a postgrad season. It worked. He landed offers from BC, Duke, Virginia and Vanderbilt. He chose Boston College, where he became the first true freshman to start at tackle in 10 years. He wound up setting a school record with 54 starts and earned a degree in biochemistry.
