I haven't watched the other quarterbacks listed but when you calculate the average yardage per attempt you will see that most of Jones attempts are on very short routes so the % of pressure is slightly misrepresentative of reality. You really sholdn''t have pressure when you're running a five yard slant. Conversely if you're attacking down field it's more likely that the opponent will generate pressure. I suspect if the play calling mimicked Mahomes and Allen that our offensive line would shoot to the top of the list.
