The physicality has been there the whole season, looking at hits per 60min to avoid games played biases.
Over the course of the season we are at 23.67 hits per 60min and ranked 9th in the league, the monthly breakdown is:
October 23.82, ranked 12th in the league
November 25.39, ranked 7th in the league
December 21.37, ranked 15th in the league
January 25.57, ranked 7th in the league
But keep in mind hits like blocked shots are those type of things that are both good and bad, it's nice to see them being done consistently but it also means you didn't have the puck.
To me the most impressive thing about our hitting is that outside of Pezzetta who hasn't gotten many games we don't have a lot of forecheckers who go out of their way to finish their checks, which usually ends up meaning a hit thrown 3s after the D has already passed the puck and generally irrelevant except to inflate the stats.
