NHL Analytics Blog

Hockey is low-scoring, and a low-scoring game is a high-variance game. A team can outshoot its opponent two to one and lose to a hot goalie and a deflection. The guides in this category are about separating the process that persists — shot volume, shot quality, special teams — from the results that do not, and about why a single month of NHL outcomes says less than the same month in basketball.

The starting goaltender is the central character. He is confirmed late, he is the largest single-game variable, and a change in the crease moves the moneyline more than most skater injuries. The guides explain save percentage, goals saved above expected and why the Sportslyx package looks for the confirmed starter first and re-derives the probability from the moved line when he changes.

Grading rules matter more in hockey than elsewhere because of how games end. A moneyline read on Sportslyx settles on the final result including overtime and the shootout, matching the market; puck-line and total context is read alongside it; a postponed game is void. The guides state these rules so the monthly record can be read correctly.
