Vader, I know you want facts, to point to and review, but watching the game on TV gives too small of a window to accurately see how putting Archer in motion effected the entire Browns Defense. I'm at the game and I have an endzone view. That D was tripping over themselves to get into position to cover Archer. It was the reason why the first screen to Bell was wide open in the right flat. It was because Archer motioned left and drew the center of the field with him, making the inside linebackers unable to get into position for the screen to be delivered. The TD has already been documented here.
Perhaps we stalled in the 2nd half because Archer was hurt, and we lost our ability to create mismatches? That may be a reach, but their D was pinning their ears back and rushing us when he wasn't out there.
