Seriously? That’s not all the offensive system is based on. Yes, it’s designed to score on the rush, but usually they do it by highly coordinated breakouts.
and part of the reason they play the defensive system they do is to facilitate those breakouts, but it's really risky and if you don't have the right players it doesn't work too well (as we've seen). My biggest criticism of AV is that he simply has not bothered to try to modify his coaching system enough to fit the players he has ended up with and that the league has either figured out his system or just generally moved on past it.
These teams haven't been as good as the ones he took over with, but that they give up so many high quality chances game in and game out is a disgrace at this point
e: I mean using the Pens as an example is a bit unfair considering the talent they have to work with, BUT they really have not had terrible impressive defenses but managed to use them to be a dangerous attacking team that's great at getting the puck out quick and back up the ice. The Pens are what the Rangers should have been evolving towards, rather than sticking with what worked in 2014
if AV is back next season. It make absolutely no sense, and his system is hot stew with ingredients I usually don`t prefer.
