Agreed.
His off-timing, hurried throws were Brady-esque. Pressure Tommy like that and his sense of timing went to hell. Case in point: The SB against Seattle, where Brady's QBR was under 30 unil Belichick sent in a pass protector assigned to take out Cliff Avril with an earhole shot. After thta, Brady had his miraculous comeback.
KC showed the way to beat SF. It takes sticky DB's and a variety of rushing strategies in the pass game, and beating the zone-cutback plays in the run game. Shanahan's run offense looks like his father's in Denver. Davis and Portis were different runners from MacCaffery, but the blocking and play designs look much the same.
One point worth considering when playing against it: All that latral running wears D lines down over the course of a game. Fresh legs, in the form of a tackle rotation, doesn't hurt. Neither does fast ILB's who can read and react to the RB's cuts.
