It's time to salute the players who have taken the most snaps and never want to come off the field.
In 2012, there were seven AFC North players who were on the field for either all of his team's offensive or defensive snaps, according to Football Outsiders. Among the division's Iron Men this season, there were four Browns offensive linemen and just one defensive player.
Here are the players who played 100 percent of the snaps either on offense or defense: Browns center Alex Mack, Bengals guard Clint Boling, Browns guard Shaun Lauvao, Browns offensive tackles Mitchell Schwartz and Joe Thomas, Steelers offensive tackle Max Starks and Steelers linebacker Lawrence Timmons.
These are the players who led their teams in snaps:
BENGALS: Boling, 1,133 snaps
BROWNS: Mack, 1,093 snaps (including 62 on special teams)
RAVENS: Michael Oher, 1,134 snaps
STEELERS: Starks, 1086 snaps
