After the 3 preliminary games being aired on KJZZ the tournament games will be aired on NBATV. I haven't heard any thing stating that the first 3 games will be aired on NBATV.
The first post makes it sound like every summer league game, preliminary or not, will be on NBATV
NBA TV will be televising all 67 NBA Summer League games from Las Vegas, including 38 games live during the event, and every game will also be available live at NBA.com/summerleague and on the NBA Summer League app via a subscription-based package.
But yeah, to confirm it I looked at their webpage and on Saturday at 830 pm mountain time the Jazz will be playing the 6ers (and the NBATv schedule mirrors the KJAZZ schedule in time, so I'm guessing it's live there too). Usually I don't give a **** about summer league though I still watch the games, and I guess I still kind of don't really, but I'm probably looking forward to this one more than any since Deron and the RMR were around.
