The cable business model was the all cable subscribers are paying for every channel, whether they watch it or not.
The streaming revolution has taken the revenues from people who didn't watch off the board for the sports teams. And that's why the teams are gonna lose a lot of revenue. That slice of the pie is just gone.
I think lots of people are confusing the distribution of TV as a "Channel" vs a "Program." The leagues can sell the games they produce as syndicated content. So the local team could be on different channels in different markets. This was done by college sports a lot in the 1980s/1990s.
You could see afternoon weekend games being bought by ABC/CBS/NBC/FOX, but you won't see the broadcast networks just being the home of 70 NHL/NBA or 150 MLB games because the affiliates are only allowed to preempt network programming a handful of times a year.
The most likely situation would probably be selling games to local Ion stations. Ion, being OTA, is available in more homes and gets higher ratings than cable networks like TNT, TBS, USA, etc. As cord-cutter numbers grow, Ion has really grown, too. Because it's free to cord cutters.
Their owner (Scripps) is looking to elevate the networks and actually has talked with the Pac-12.
Ion and the leagues talking could be a win-win.
I want the record to reflect that I said this BEFORE seeing the Bucci tweet.
