Yeah, exactly, but what IS a good stat or correlation of a star RB or an adequate RB or a shitty RB? One answer is you know them when you see them. There are so many factors, though, it's really hard to say: quality of the O Line, type of offense, other star or quality players to share attention of the D, etc. The thing about Lacy that is impressive to me is that he still looked good even when Rodgers was hurt and defenses could really focus on him. The thing that does not impress me about him is he can't seem to break loose for a big play - something which yards per carry is an indicator of. We're better off with Lacy playing most of the downs than any of the previous RBs including Starks, but he's no Jim Brown either or Adrian Peterson in his prime either.
