It wasnt just a consistent pass rush. It was a contained pass rush. TB did not allow Mahomes to roll left or right or step up. A team can get all the pressure they want on Mahomes, but if he is allowed to step up or roll out it doesnt do any good, he is too good on the move. They forced him backwards, which probably did more harm than good for Mahomes. He would have been better off just making a quick read and throw. TB plan had Mahomes tendency to escape too early really working against him.
