I suppose, on a personal level, I'm more partial towards NBC's coverage since I have a better memory watching it than with CBS'. CBS' NBA coverage in my estimation, hit its stride in 1982-83, when Dick Stockton became the lead play-by-play man, CBS treated the coverage as a must see event (rather than the oft-taped delayed, redheaded stepchild to their NFL or golf coverage), and they introduced the dynamic theme music/opening sequence. NBC's peak, I suppose was 1990-91 through 1997-98 (before the lockout and the end of the Michael Jordan era Bulls' dynasty).
And if the Jordan era, as well as the Houston Rockets' back to back titles sandwiched between Chicago's dominance, and the Shaq-Kobe era Lakers winning three straight titles (to close out NBC's coverage) defined the NBA on NBC era, then it's pretty safe to say that the NBA's reemergence under Larry Bird and Magic Johnson as well as the Detroit Pistons' "Bad Boys" era defined the later part of CBS' coverage. http://the506.com/yabb/YaBB.pl?num=1242682212
