Whether Disney is a mega-corporation or not, the numbers are the numbers.
The next time rights fees negotiations take place they are likely to scale back.
This is going to trickle down into payroll budgets for teams, leading to potential work stoppages, etc.
The other side of it is that ESPN is trying to build its ESPN+ streaming service, and it's competing against YouTubeTV and Amazon. Those two services have much smaller personnel budgets. So ESPN is scaling back on its on-air staffing, while converting their content for streaming. At some point, they're going to put more of their content behind a pay wall that consumers can only view by subscription.
The point is ESPN is negotiating with the same teams and leagues for streaming as they air for the channel. So I don't expect the teams or leagues will be experiencing any cut in rights fees, as long as there are other platforms for their content.
