I think this is it. Remove Lamar and put a decent to good QB behind center for the Ravens - a Jared Goff or Baker Mayfield - and they'd probably still have a winning season with their defence accompanied by the likes of Henry, Hopkins, Flowers, Likely (when available). Would the Bills in that scenario? I have my doubts.
That's not saying Lamar isn't class - he clearly is. But his support, like Joe Burrow's, is at another level.
