If the 49ers are smart, not stupid like Ivan, they take a page from the NE Pats 2018 AFCC.
KC won the toss and deferred. So, the Pats basically burned up the entire 1st quarter with 2 drives holding the ball for 12:33 scoring a TD on drive # 1. KC only had the ball for 1 drive worth 2:00 + minutes. Keep Mahomes on the bench. Mahomes is the real NFL MVP and the best player on the field and Purdy is no match for him. Try to keep the KC offense cold and the KC defense tired and depleted like a Tesla battery.
Secondly, whatever was successful for SF in the 1st half, be ready to abort it because the KC defense will take it it away.
