The Bills are 20th in the NFL in rushing yards per game - and had 144 less rushing attempts than Baltimore. Their run game is really a short/quick pass game underneath, in order to work you over the top later in series/games. But the run game is not something to fear heading into Saturday. Making Josh Allen uncomfortable, and containing him when he breaks the pocket is key here. Can't beat Josh Allen if he's able to break the pocket without consequence, or even worse, stay in the pocket and go through his progressions.
Beasley got dinged up a bit in the game on Saturday. He and Diggs are Allen's favorite targets, but Beasley, in particular, on the short passes.
Bills are 17th in rush yards per game allowed. They're 13th in passing yards per game allowed. They're 16th in points allowed. They're 15th in sacks. This part seems flukeish to me given everything else, but they are 3rd in takeaways and 4th in turnover differential.
Basically, the Ravens should be able to score on Buffalo - this game, to me, will come down to how much they are able to contain Allen and the Bills one dimensional, yet really good offense.
