The Indianapolis Colts have signed their top pick in the 2011 NFL Draft, former Boston College offensive tackle Anthony Castonzo, to a four-year deal worth $8 million.
While the first three years of the contract are guaranteed, the fourth is not, according to a tweet from ESPN's Adam Schefter.
Castonzo entered Boston College as a tight end, but quickly made the transition to tackle, where he became the first true freshman to start in 10 years. The 6-foot-7, 308-pound lineman went on to start a record 54 games for the Eagles.
Castonzo was drafted by the Colts with the 22nd overall selection.
