I still don't consider the season over. All the "6 teams have ever made the playoffs after 0-3" stuff is a fundamental misunderstanding of probability theory.
But they're in their biggest hole ever with two home losses to teams that we'd penciled in as "yay, easy schedule" teams. If there's any lane, it has to be the defense had its worst game of the season against Washington, and even if it's below-average it cannot be like that ever again. I think that's within the "reasonable" range of possible outcomes, as long as the offense doesn't decide to shit the bed whenever that turns around.
Tons of ifs and coping and hoping, but I won't count out any Joe Burrow team this early.
