I don't think the Chiefs needed confidence in anything, they just needed a break which would have come sooner or later. Go for it and not make it, that's a break they need. Make a touchdown, it might be demoralizing, but does not put the game out of reach. As it stood, the defense still had a 24 point lead to work with, and they couldn't hold it. I understand some of the criticism, but it still seems silly to me given that all indications were the Chiefs were able to score at will after the first quarter. This one play was not going to be a catalyst for anything given the end result was a blowout going the other way.
