Close. NBA Live 99.
The idea of games not shown on TNT not having commentary is interesting, but my suggestion would be to have Albert and Fratello doing the nationally televised games, while other games would just be the local network (and thus, the home team's TV analysts) - for the sake of being generic, they could use Don Poier and Bob Elliott in those roles.
But then again, that would waste the use of Marv Albert and the Czar, if they would only commentate a handful of games.
