The metric is measuring blocked shots, penalties and hits, areas where Girardi is pretty good. To say because of this the criticism of him is unfounded however isn’t really true.

Did you know Girardi leads all Rangers in shots that were blocked @ ES? Interesting, Cally is 3rd on that list also. Of course, he’s had a better season overall than say, Redden.

And obviously Cally is going to lead this list. He’s among the league lead in hits, BS, and he doesn’t take many penalties, and he’s even taken some faceoffs

It’s an interesting list, and certainly could be used as tiebreakers between players I guess (say, the everlasting Dubi/Cally debate), but it’s like anything else, it’s just one reference point in a body of work.
