I agree with the OP. Yeah, I doubt the playoffs are happening this year, but it's not the most off-the-wall scenario. Until they are officially eliminated, the Bills should be playing as if they still have a chance, however slim. If they don't, then that's on them and the coaches.
I have been disappointed with some of the responses from players this week that indicate that the players do think the season is now lost. Perhaps that is the snarky media feeding into and trying to be realists, but still...
