The Indianapolis Colts were hit with devastating news when left tackle Anthony Castonzo revealed he would be retiring when the 2020 season concluded.
The announcement came as a surprise to seemingly the entire organization as Castonzo enjoyed an extremely productive campaign, earning a superb 80.8 pass-blocking grade from Pro Football Focus, all the while conceding just two sacks and two penalties across 749 offensive snaps.
That efficiency indicated Castonzo would play out the duration of the two-year extension he inked last offseason, but it evidently wasn’t enough to convince him to put his body through another grueling campaign after he underwent season-ending ankle surgery in December.
