I haven't seen the good that Richman has done because I am usually looking at the RB getting yards in those cases. But when Richman screws up (usually pass blocking), it's bad. Very bad.
Take it for what it’s worth, but sites that grade linemen have for the most part graded Richman fairly well as far as I know. So when there’s stuff where it looks like he screwed, idk if he got left out to dry by another guy missing an assignment, or if he simply graded out better in other ways to even it out.
