The Colts have picked up their fifth-year option on Anthony Castonzo, according to Will Brinson of CBSSports.com (via Twitter). The move will keep the team’s starting left tackle under contract through the 2015 season.
Castonzo, 25, took over the Colts’ left tackle job on a full-time basis shortly after being selected by the club in the first round of the 2011 draft. In 2013, he ranked 27th out of 76 qualified offensive tackles, according to Pro Football Focus’ advanced metrics (subscription required). Castonzo’s PFF grade was buoyed by solid run-blocking and an ability to avoid taking penalties.
