I just wrote a whole post about that chart but realised that it was too preachy. But the gist of it is that that is a bad data visualisation. This fantasy guy plays with the scales to make small differences seem much larger. He did it with run block win rate earlier this season. When scientists do this it’s called data dredging or p-hacking.
According to that chart, they are giving up .7 yards per carry more than the league average. Not even a whole yard.
