Via the eye test, Grossmann can appear to be the Flyers' best pure defensive defenseman. To start, the Swedish blueliner generally avoids the egregious positioning errors that plague the Flyers at times. He is always among the team leaders in blocked shots. He plays physical without taking himself out of the play, unlike his sometimes overaggressive teammate, Luke Schenn. And overall, he seems to have a calm, controlled demeanor in the defensive end.
But maybe Grossmann gets a bit too comfortable in the defensive zone. After all, he's by far the worst Flyers defenseman at escaping it.
Thanks to the work of Pierce Cuneen (@pcuneen19) and @2_for_slashing, defensive zone exits have been tracked for each Philadelphia Flyers game. Total exit attempts, successful exit percentage, and successful exits with possession have all been recorded.
The numbers are not flattering to Grossmann.
He ranks last among Flyers defensemen with a successful defensive zone exit percentage of 66.8 percent. So for every three chances that Grossmann has to clear the puck out of the defensive zone, he fails to do so at least once.
It gets even worse when it comes to zone exits with possession. Only 31.1 percent of Grossmann's zone exit attempts leave the defensive end successfully and also see the Flyers retain possession of the puck past the blue line.
That's by far the worst on the team -- a full eight percentage points worse than any other Flyer. A majority of his "successful" zone exits lead to results such as misfired passes, harmless neutral zone clearing attempts that go right back to the opposition, or icings.
Grossmann may make fewer obvious mistakes in his own end than other defensemen (debatable, but possible). But when his inability to clear the zone results in extended cycles and repeated opponent possessions, shots and chances continue to add up. Eventually, some of those constant chances are bound to become goals.
