May 31, 1983: After Philadelphia went a league-best 65-17 in the regular season, Moses Malone predicted the 76ers would sweep the playoffs and win the NBA title, saying they’ll win each series in four games — “Fo, Fo, Fo.” He wasn’t that far off — the 76ers lost just once on their way to the title. They swept the Lakers in the NBA Finals to avenge losses to Los Angeles in 1980 and 1982.

1983: Philadelphia’s Moses Malone wins his third and final MVP award all in a five-year span. He won the first two with the Houston Rockets. One of the most successful players to skip college and go pro, he averaged 22.7 points and 13.4 rebounds that season.

The Celtics tied a single-season league record of 33 consecutive home victories, including playoffs, set by the Minneapolis Lakers in 1949-50.

May 21, 1986: Ralph Sampson’s tip-in at the buzzer rattles in, lifts Houston past the Los Angeles Lakers and vaults the Rockets into the NBA Finals.

May 7, 1989: Michael Jordan’s hanging jump shot over Cleveland’s Craig Ehlo beat the buzzer and gave the Chicago Bulls a 101-100 playoff win over the host Cavaliers. Jordan drove left, pulled up near the free-throw line, outlasted Ehlo in the air and drained the game-winner. Jordan’s celebratory leap and fist pump as Ehlo crumples to the ground is iconic. The win clinched the first-round Eastern Conference playoff series 3-2.
