The Pittsburgh Steelers have played eight games during the 2018 regular season. Matt Feiler has started three of them at right tackle. I’m pretty sure nobody was expecting that, especially not after they drafted Chukwuma Okorafor, and they still had Jerald Hawkins.
Feiler, in his second year on the 53-man roster, spent his first three years in the NFL on practice squads. He was given the opportunity to start the season finale at right guard last year and played well, and has been the backup tackle so far this year as well, showing the capability of playing all up and down the line.
