NBC airing Sunday night games shouldn't be the only addition. As I stated before, CBS should be given the rights to Saturday night games, with ABC continuing to air games on weekend afternoons, now supplemented by an early Saturday afternoon game on Freeform at around 12-1 PM ET starting in January.
CBS games would be co-produced by WBD Sports, while CBS and WBD would now begin to co-produce games on TNT, with CBS games also using the longtime TNT theme in place since 2002, thus expanding the CBS/WBD partnership beyond March Madness.
ABC, CBS and NBC would alternate rights to the NBA Finals. This would leave Fox as the only big four network not airing NBA games, and with good reason. Though NBC could license Roundball Rock from Fox.
