"27. DALLAS COWBOYS
Randy Gregory will have an opportunity to finally put it all together as the starting left edge defender in Dan Quinn’s new defense in Dallas. The first six years of his NFL career have featured up-and-down play and extended suspensions, but he was playing the best football of his career down the stretch of 2020, earning an 80.5 overall grade on his 270 defensive snaps. He still needs to show he can play up to that level as a starter over the course of an entire season.
While Dallas' edge group features some promise, the team needs several interior players to take big steps forward.
The Cowboys allowed 2.3 rushing yards before contact per attempt in 2020 — a half yard more than any other defense in the NFL." (I bolded this part)
This is per PFF, so some will discount it, but I feel it's pretty spot-on.
The last sentence is telling. A massive embarrassment.
