They won by having an exceptional quarterback named Patrick Mahomes. The Chiefs also have a team that is unfazed about playing from behind. See the results of the AFC playoff games. It is no fault of the Niners head coach, his team just got beat by a better one. Go Chiefs!
You are right, all the year the team has come alive when it had to. As a hometown guy, I was never worried. I actually said they’d regret it when SF posed for their Sports Illustrated cover shot with a lot of time left in the game.
This team doesn’t know how to quit, get a great running back and some defensive tweaks next year and they could go undefeated. It seems like sometimes Mahomes plays conservative till he has to, then gets turned loose and scores, while the defense never laid a hand on Garropolo till the game was on the line, then they were all over him.
