Though a wide receiver in college, Mike Tomlin’s coaching upbringing has focused almost exclusively on the defensive side of the ball. Since becoming Arkansas State’s defensive backs coach in 1998, a chance to bring his receiver background and teach secondaries how offense’s think, Tomlin has been a defensive guy. That’s remained true through this season, one of just a handful of NFL head coaches with that type of resume. While he doesn’t carry the title, we know Tomlin has a significant influence on the defense, either calling its plays or having a heavy hand in the process from a gameplanning and in-stadium standpoint.
