If anyone on the 49ers' kept it's own O in check, it would be Kyle Shanahan. After building a run heavy team that allowed them to dominate in the regular season, he starts the game with a pass heavy game plan. After switching to a run heavy plan, they got a 10 point lead with 2 1/2 to go in the 3rd. Switching back to pass heavy led to the collapse of the 49ers' O giving Mahomes the Chiefs' O the opening they needed to score 21 4th quarter points.
