Re: 8 rokus and streaming the superbowl on all 8 televisions
The Super Bowl is being broadcast by NBC, so streaming choices will likely be limited. Any of the providers that offer your local NBC station, such as YouTube TV or Hulu TV will probably have it. NBC offers their own streaming service (Peacock), so it might be available there as well. But if you can get your local NBC station with an antenna, that's probably the best choice.
