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

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.

The Pittsburgh Steelers were largely unimpressive as they suffered a 29-10 loss to the Kansas City Chiefs on Christmas Day. Several members of the organization spoke bluntly about the team's recent play.
