I know, but it's not always easy when you have no room for error in the fourth quarter.And yes in 2008 the steelers had a lot of close game and close win, but for the most part it was against very good teams, especially in the second half of the season.If we just look at the points differential, it was still better in 2008 and 2010 than it was in 2017.
As another said, a 13-3 team finished without a problem with a points differential over 100.It was not the case for the steelers in 2017.
