I thought they could go 4-1 in this last stretch before the KC game and obviously still think that. The only difference now is 4-1 pute them at 10-6-1 with a shot at the playoffs while with a loss to KC they would've been 9-7-1 with almost no shot.
Going 5-0 seems very unlikely but if they can pull out the Lions game, maybe.
I don't think anything more than one playoff win is realistic though, my main focus is on seeing the defense continue to improve and show signs of being a unit that could be good enough to make a big run next year with some additions.
