After playoff run ends, will Mike Tomlin walk away from Steelers?

Before the Bengals-Steelers game in Week 16, we reported on NBC's Football Night in America (and posted here) that: (1) the Steelers will not be firing coach Mike Tomlin (who at the time was caught in a three-game losing steak); (2) the Steelers intend to extend his contract after the season; and (3) the Steelers had received no indication whatsoever from Tomlin that he wanted to do anything other than continue to coach the Steelers.
