INDIANAPOLIS — The Colts stumbled on the idea of using Quenton Nelson as an emergency left tackle almost by accident.
Nelson, arguably the best guard in football, hadn’t played tackle since he backed up Zack Martin, a former Bishop Chatard star and current Dallas Cowboys lineman, in his early days at Notre Dame, but the injuries that hit Indianapolis on the offensive line the past couple of weeks forced Nelson to play a little left tackle on scout team.
The Indianapolis coaching staff liked what they saw.
Liked it enough that after they lost Anthony Castonzo and Le’Raven Clark in back-to-back weeks, the wheels started turning.
