The Pittsburgh Steelers lost. Yes, they should have won. Yes, it doesn’t feel great when they lose. It’s also one game, they’re in the exact same position that they were in before kickoff—in control of the number one seed, that is—and they have plenty of time to get better. Losing one game doesn’t mean losing a bunch.
After all, how often does a team win its first 11 games of a season? Not incredibly often. The fact that they held out this long without losing a game is a pretty remarkable achievement, especially when you considering the fact that their previous best was 7-0, which came all the way back in 1978.
