Only Canadian forwards, about 20 per season during O6 and then at least 40 per season from that onwards.
Results are preliminary so far, but a few notes. There seem to have been a large increase between 1971-72-73 (WHA started, NHL expanded from 12 to 14 teams using a balanced schedule meaning getting to play 12 more easy games). The 1973-74-75 also seem to indicate a change (NHL going from 16 to 18 teams, and Washington allowing 446 goals in 80 games, while WHA still existing).
Are the increases in actual or adjusted PPG?

There were distinct increases in '73 and '75, after a huge increase in '68. After '76, there appeared 6 successive decreases.

Do you think ages 23-27 is a bit restrictive?
