Kyle Shanahan abandoned the run when the 49ers had the Kansas City Chiefs on the ropes.
If he had just stayed with the ground game, the 49ers would have run out the clock, demoralized the Chiefs and the 49ers would own their sixth Lombardi Trophy.
Instead, he enabled Kansas City to rally from a 10-point deficit for a 31-20 victory in Super Bowl LIV on Sunday night at Hard Rock Stadium in Miami Gardens, Florida.
Everybody is looking for aspects of the 49ers’ loss to second-guess and find blame. It comes with the territory.
