Most of these are just coincidences because of personnel issues.
My favorite aspect is his implementation of the forecheck. The Devils forwards are challenging the opponent's defensemen rather than challenge the forwards in the neutral zone like lemaire.
It makes more sense because the current trend is using young, inexperienced Dmen who have the physical tools to succeed when not pressured.
Unfortunately it doesn't work as well against veteran Dmen. Their best offensive games have been against the likes of Justin Faulk, Jack Johnson, Keith Aulie, Luke Schenn, and other similar players.
