TBS began their affiliation with the NBA in 1984-85.
In 1986, neither TBS or CBS carried Game 1 of the Eastern Conference Finals, relegating that to local TV. This would be the last time any NBA Conference Finals game was not aired on a national network.
During the 1989 NBA Playoffs only 13 of the 24 Games 1-3 in Round 1 appeared on TBS or CBS. For example, none of the four games from the Seattle-Houston first round series appeared on national television.
I think your mistake the 80 lakers/Sixers game was show live. The last tape delayed game was 79 Bullets/Sonics . But that was 30 years ago I could be wrong.
