Well, I guess I'll step up to talk Colts. Definitely one of the worst games they've played this year. Luck was surprisingly off. KC's defense played a lot better than I thought they would. So, the Chiefs move onto their first AFC title game since the 93 season. Mahomes' Chiefs are not the Chiefs of old.
As for the Colts, they had a far better year than expected with an extremely young team and a rookie head coach. Get Luck some more weapons and they'll be fine for the foreseeable future.
The Colts will be a good team next year. If the Texans fix their offensive line, they could be as well. If the Jags ever get a decent QB, they could be dangerous. The Titans, I don't know. I don't trust their head coach to help them out as much as they think he will. The AFC South could potentially be a very tough division to play in.
