Colts left tackle Anthony Castonzo contemplated retirement after the 2019 season but called it quits in 2020 after an injury forced him on the sideline for a few weeks.
The Colts offensive line has consistently been one of the best in the game since Chris Ballard took over in 2018, and the unit will presumably continue that legacy in 2021.
