‘Leslie Frazier vs. Philip Rivers. It’s hard to imagine the Bills completely shutting down the Colts’ run game. The question is: How much pressure can Frazier manufacture on the immobile Rivers when the Bills get the Colts in obvious passing situations. The Colts have one of the top two guards in the NFL in Quenton Nelson and one of the top centers in Ryan Kelly. Pressure up the middle won’t be easy, but it’s the way to impact Rivers. Look for the Bills to show a lot of A-gap pressure (on either side of the center). In the win over the Titans, Tennessee rushed four and sat back in zones all day. That’s not the way to go. Rivers was 29 of 39, and 27 of his completions were within 10 yards of the line of scrimmage. Rivers has been sacked at the third lowest rate in the NFL. Sacking isn’t key. Making him feel heat is.’
