I agree with the elimination of divisions and going with 4 conferences.
2 x 24 = 48 non-conference games
4 x 7 = 28 conference games
While I would be good to stop there are 76 games I agree with
@tarheelhockey that maximizing revenue is a guiding principle.
Reduce to 80 but go with 4 rivalry games. Rivalries would help sell out games and build media hype.
For the Canadian markets it could mean an extra game vs your non conf CDN teams. Get Detroit and Chicago to play more often... Get Arizona to play... Umm teams willing to play Arizona. Whatever makes more $ and better TV and fan experience.
Playoffs are strict 1v4, 2v3, reseed for final 4.
Removing 2 games from schedule would also allow for a 4v5 play in if the league really wanted.
Here's my kicker. Draft pick ranking would be based off of only the 2x24 outer conf games and 2 first x 7 conf games, eliminating the 3rd and 4th conf games from the ranking. That way draft ranking is based on a 2x balanced schedule.
