"I believe that Mike Tomlin is unfireable," former Pro Bowl safety Ryan Clark said Thursday on ESPN. "I believe if Mike Tomlin steps away from being the coach of the Pittsburgh Steelers, that should be his decision. And I've said time and time again: I do believe that should be the decision that he makes.

The ESPN analyst and former Steelers player suggests Mike Tomlin's voice has "run stale" despite the coach never producing a losing season in 17 years.

This year, one of those complaints is coming from Steelers owner Art Rooney II.  During an interview with the team's official website, Rooney revealed there's one thing on the schedule that he's not too crazy about.

For the second straight season, the Pittsburgh Steelers have the toughest end-of-season schedule, according to analysis by analyst Warren Sharp.

Pittsburgh Steelers head coach Mike Tomlin has been nothing but steady since he began his tenure in 2007. Over the past 18 seasons, the squad has gone at least .500 each year and won Super Bowl in 2008 (and lost in the Big Game in 2010).
