It seems like we are better at winning in an offensive system than we are in a defensive system. I realize defense is important, but it seems like it would be better to ride offense to the playoffs, get beat because "that's not playoff hockey", and then adjust and refine the roster from there as opposed to wasting another year missing the playoffs while trying (and losing) to teach a team to make the playoffs winning 2-1 most nights.
A lot of teams make the playoffs with an "all offense" system, then get humiliated by teams that play defense, and then adjust and improve. Remember when Columbus swept Tampa? Remember when Florida moved on from guys like Huberdeau and Duclair after winning the President's trophy and getting whooped in the playoffs? Which team ever made the playoffs with a negative goal differential? Who are we modeling our game after?
