Because it's not worth the increased risk of injury and massive loss of energy in any one regular season game to be worth going all-out. In the playoffs, every game, every play, matters so everybody steps up that little bit. Players get to pucks a little faster, which takes space away for offensive creativity, and players can take more liberties because of how the game is called.If defense is so easily played that the playoff switch suddenly turns it on, then what is the excuse for not flipping that same switch in the regular season?
You also learn player tendencies, team systems, and how to play to one team specifically, instead of learning an overall defensive style that has to loosely apply to all teams. Line matching also gets a lot tighter, as we saw last year.
There are a lot of reasons. It's not just a switch that teams put on. A lot of it has to do with the different style of play in the playoffs that naturally creates an environment where it's easier to defend and harder to score.
People also forget we should have our 3rd-line center back by then. We just MIGHT be better defensively with our checking center.
