Each time the NHL has added teams - from Vegas in 2017 to Seattle in 2021 - the league has seen a notable rise in goals per game. This is partly due to weaker players entering the talent pool, creating more opportunities for the top stars to excel. Historically, each expansion has pushed up league scoring, typically by 0.12 to 0.4 goals per game, with the 2021-22 season showing a jump to 6.28 goals per game.
This scenario could increase excitement for the game, but expansion isn't without risks. Strategic shifts could counteract rising scoring, and adding too many replacement-level players could dilute overall talent. Still, for a league eager to grow its footprint and revenue, the scoring surge that comes with expansion may be seen as a positive side effect.
Ultimately, more teams could mean more goals, a bigger star spotlight, and a more thrilling product for fans.
