In soccer, Manchester United lost 7-0 to Liverpool recently. They haven't lost since, qualifying for the next round in two separate competitions. The defeat was an embarrassment where every player bottomed out, but it didn't and hasn't defined their season. It doesn't mean they don't have issues to sort out in the long term but they are one of the best teams in England. That's very much like the Bills post Bengals. The big difference is Manchester United only had to wait four days for the next game, rather than close to eight months of it eating away at the players, staff and fan base.
