The 1980–1981 season was arguably the rock bottom point of the tape delay era for CBS. CBS aired four of the six Finals games on tape delay and six of nine during the Conference Finals. Just like the previous year, CBS scheduled Games 3 and 4 of the NBA Finals without an off-day to avoid yet another tape delayed game. CBS wanted the Pacific teams to advance in the playoffs so that they could show live games at 11:30 p.m. on the Eastern U.S.; however, the Los Angeles Lakers and Portland Trail Blazers were upset in Round 1, while the Phoenix Suns were upset in Round 2. This left two teams located in the Central Time Zone, the Houston Rockets and Kansas City Kings, to play in the Western Conference Finals.
