He was before my time so I am curious

Did he lose 3 ten point or more leads in those games as the primary offensive play caller like Kyle Shanahan has now done in 3 Super Bowls?

I love what SF does offensively with pre snap movement and use of personnel. Their run game is great to watch with the blocking variations they use and when they are clicking there isn't much you can do to stop them. Shanahan deserves most of the credit for that along with Lynch for the pieces he has assembled. With all that said Shanahan is now in Lamar Jackson territory for me. Until I see him close the deal, I won't believe he can. He should have a couple of Super Bowl rings and he doesn't with significant reasoning being his own decision making.
