The Chiefs are probably a better team right now. They have a better QB. Their roster is probably better overall too. Better coach. Probably a better staff. If you replayed that game 10 times we'd probably win less than half.
I think the way to look at it is the Colts stole a win there. So that means if you are looking at the game and feeling unhappy with it, no need. Things aligned and the Colts did enough to get a badly needed W. Get drunk, order up some hookers and blow, or door dash if you swing that way and carefully sip a cold one.
