I really do not think that Spectrum would be able to televise a game without buying the rights from ESPN or CBS., and why would they pay for at least a CBS Sports Network Game when it is already on their system. With the move to ESPN+ they are also unlikely to give a game away.
Also Spectrum would take away a game from everyone who has Directv or Dish Network, reducing the amount of people who could watch the game from where it is streaming.
