I’ve said this before, but the Bills coaching staff doesn’t mind being ran on. They invite it.
Sure, they don’t want to give up 10 ypc or something insane, but they purposefully give opposing offenses the run lanes and essentially play chicken with them to do it all game long.
What typically happens is that the opposing team ends up with a ton of rushing yards, but with the Bills offense scoring 30+ points each game, the opponent eventually has to abandon the run to keep up points wise (and have enough time).
When you have a top 3 offense, giving up the run can be to your advantage and the Bills do it masterfully.
“You want to run on us? Go right ahead.” - Bills coaching motto
