And that all doesn't take into account the most profitable property- The media revenue. TV, radio, SN.ca etc all brought in record breaking numbers. Like you said, not all of the revenue will show up this season because regular season TV ads are already purchased for the most part. But when you get 30 million viewers for the playoffs that is worth a ton of money.
To put it in perspective the Ottawa Senators get paid around $30 million per season by TSN for the regional TV rights to around 60 games per year. The average viewership of the games is 200-250K. So that is about 15 million viewers over the course of the season and they get paid $30 million. Well SN just got more than that for the postseason alone.
