Perhaps, but I don't think the sports leagues and other video content providers will ever agree to letting their IP be devalued that way. They see what happened to musicians and record labels with Spotify as a cautionary tale, not a model to emulate.

Otoh, maybe Netflix and other streaming video services will start their own sports leagues in order to vertically integrate and own everything end-to-end just like what they did with TV and movie production. It would be tough and expensive but maybe not impossible?
