about going for it on 4th down. The strength of the Niners is their defense, not their offense. As hard as can be to stop Mahomes when he needs to score, I think I would trust them to get a stop more than I would the SF offense to get a critical 1st down or TD against the Chiefs' defense, which was one of the best in the NFL this season (although underrated, presumably because people usually think of the offense and Mahomes when they think of the Chiefs).
