Steelers head coach Mike Tomlin is not concerned about the arguments the team's defense had after losing to the Chiefs.

Pittsburgh Steelers HC Mike Tomlin and his coaching staff appear to be under fire again as the team prepares for Week 18 and the playoffs.

It did indeed. The Steelers offense was held back by poor play from quarterback Russell Wilson and far too many unforced errors by the offensive line. On defense the news was no better with Chiefs players running wide open in the passing game and quarterback Patrick Mahomes with far too much time to make plays.
