Look at it this way, ABC has ESPN to rely on when there’s scheduling conflicts on the national network. What do the other major networks have? You’d be seeing games on NBC Sportsnet or some shyt.
I’ve had this thought but maybe have CBS/TNT team up for the Finals like they do for March Madness and that can provide another major outlet. In my perfect world, NBA would be evenly distributed between Fox, NBC, CBS/TNT, and ABC/ESPN on some NFL shyt.
