The Pittsburgh Steelers were 9-6-1 during the 2018 season. We know it. The NFL knows is. The Steelers especially know it. And more to the point, they are acutely aware of the fact that their 9-6-1 record was insufficient to qualify them for entry into the postseason, the first time since 2013 that they faced such a fate.
The last time that the Steelers had to come out at the end of a season and talk about their record was in 2013, when they finished 8-8 and not good enough to make the playoffs. That is generally the only time that they refer to their performance by mentioning their record—other than, of course, when they got 13-3 and lose in the first round of the playoffs.
