That really is dependent on the channel that game is on as they usually put that on at least 4 different broadcast channels, (CBS, TBS, TNT, TruTV) which also depends on whether you have those channels as part of a subscription package that allows you to watch them as TBS, TNT, TruTV requires a cable or sat subscription (which means Comcast, Spectrum, DirectTV or one of the other streaming service packages that includes those channels, such as Hulu, etc). CBS may be broadcast for you locally via antenna or you may find it broadcast as part of a free live channel that includes the games on that channel, but I would suspect the free channels may not include NCAA games due to restrictions.
CBS sports also have a website to watch the live games, but I am don't recall them having any game replays unless they have added that in recent years. I know they post highlights, but I don't remember them posting any games after they finish.
