Mike Tomlin approves of the NFL's increased emphasis on taunting penalties this season.

"We're just trying to clean our game up," Tomlin, a member of the NFL's competition committee, said. "We embrace the responsibility that comes with being the role models that we are.

"This game being played at the highest level, we understand that people who play at a lower level watch us and often mimic the things we do and how we conduct ourselves and just largely as a league competition committee specifically, there was a desire to improve in that area. That's been expressed to our guys. "

The Steelers have not been called for a taunting penalty this season, but they benefited from a critically timed flag in the 29-27 win against the Chicago Bears on Monday night.
