Anthony Castonzo was drafted back in 2011 to try to solidify the left tackle position. The position had been in flux since the retirement of Tarik Glenn. Castonzo was brought in to help keep Peyton Manning upright and keep the offense moving forward.
Fast-forward to now, and Castonzo is still tasked with keeping his franchise quarterback upright. Only now it’s Andrew Luck behind center. Castonzo has been the Colts’ most reliable lineman since he was drafted, and he’s the only one left from that 2011 offensive line. He’s the only one left from the 2016 line too.
