Or not.

The problem with hockey analytics is twofold.  1st, the #s don't tell you anything you could not just as easily ascertain by just watching the game(s); and 2nd, it's been shown statistically that around 75% of determining which team is going to win boils down to goaltending and luck.

In other words, who or which team has the puck matters just a bit above squat.

Hockey, unlike say baseball, does not reset on each and every pitch; it's continuous action.

When 75% of the determinants for winning are not within the realm of analytics, which is a fact, then its influence is wildly overblown by those wanting to sell their own version of snake oil.

Good for them, they have taken advantage of the old adage that there's a sucker born every minute.
