The last time scoring was this high consistently was the early to mid 90s. It’s gone up ~15% since OV nearly got 70 in 2008. I never tried to claim it was historically higher than the 80s. It’s just definitely higher than average.
It's around average in league history. Around the mid-point. This year is lower scoring than last year so far.
Statistically, Matthews is nearing the greatest even-strength goal scorers of all time. This is his 5th season leading the league in even-strength goals, the record is 6.
Matthews is disadvantaged by playing on a team that gets among the least powerplays every single season. Since Matthews entered the league, the Maple Leafs are 27th in PP opportunities/GP.
Ovechkin played in a lower scoring season than this one, yes, but he got way more PP time by playing on the team that got way more PP's + he plays more ice time on the PP than most other players did.
Ovechkin played 5:37 PP time per game in 07-08 when he scored 65.
Matthews plays 3:14 PP time per game this season.
So yes, higher scoring league than 07-08 but Ovechkin played 2 more mins every game on the PP.
