But while Justice looks to be a favorite to start at right tackle, McGlynn played sparingly for Cincinnati last season, mostly because of injury Bobbie Williams.
He started the Bengals final three regular-season games and their playoff game at right guard, and was also listed as the backup to Kyle Cook at center.
Four of the Colts top-five interior linemen from the end of last season are not under contract: center Jeff Saturday, guard Mike Pollak, guard Jamey Richard and Ryan Diem, who shifted inside last year after a long tenure as the right tackle.
Ben Ijalana, who missed his rookie year with an early knee injury, could be in the guard mix going forward, particularly if Justice proves solid at tackle.
Will McGlynn be more than depth?
We’ll have to see who else Indianapolis winds up with and how they all play.
