Houston Rockets

Prior to the season, the NBA moved the Rockets and San Antonio Spurs from the Central Division of the Eastern Conference to the Midwest Division of the Western Conference. The Rockets and Spurs traded places with the Chicago Bulls and Milwaukee Bucks. The Midwest Division also took in the expansion Dallas Mavericks.

The Rockets that season were led by Moses Malone, who practically carried the Rockets to the NBA Finals. Meanwhile, Calvin Murphy, the shortest player in the league at the time, set two NBA records, sinking 78 consecutive free throws to break Rick Barry's mark of 60 set in 1976 and achieving a free-throw percentage of .958, breaking Rick Barry's record set with the Rockets in 1979. Other key contributors of the 1980–81 team were Rudy Tomjanovich, Robert Reid, Mike Dunleavy Sr., Allen Leavell, Billy Paultz, Bill Willoughby, Calvin Garrett, Tom Henderson, and Major Jones. The Rockets clinched the last spot in the playoffs on the final night of the regular season following a loss by the Golden State Warriors to Seattle, as Golden State had the tiebreaker over Houston.^[1] Houston tied with Kansas City for second place in the Midwest behind San Antonio with a regular season record of 40–42 (this would be only the second time that an NBA team with a losing record would make the Finals, after 1959).

Houston's playoff run began by drawing the defending NBA champion Los Angeles Lakers and Magic Johnson in the first round. The Rockets upset Los Angeles, two games to one, with the Rockets winning both games in Los Angeles. The Western Conference Semifinals matchup featured the Rockets against the Spurs and multi-year scoring champion George Gervin in a Texas Shootout. The Rockets would win the series in seven games behind strong contributions from Murphy and Reid, including Murphy's career playoff high of 42 points in the climactic Game 7 at San Antonio. This set up an unlikely Conference Finals matchup with Kansas City, being that both teams finished the regular season with identical losing records, together compiling just 80 total victories of 164 games played. The Kings, led by Otis Birdsong, Scott Wedman, and Phil Ford fell to the Rockets in five games, and the Rockets would break into the NBA Finals for the first time, the first of four in franchise history. It would be the only time two conference finalists in the playoffs both had losing records, and the second and last time to date a team with a losing record made it all the way to the Finals round (the first being the 1959 Minneapolis Lakers).

Boston Celtics

This was the Celtics' first appearance in The Finals since their 1976 championship winning team against the Phoenix Suns. The Celtics were not quite the same team as five years before, as they added the likes of Larry Bird, Robert Parish, and Kevin McHale, a trio that would come to be known as "The Big Three." M. L. Carr, Cedric Maxwell, and Nate Archibald were also capable players off the bench, and key cogs in Boston's balanced offensive attack. However, the Celtics lost future Hall of Famers Dave Cowens and JoJo White to retirement. Still, the Celtics, led by Bird, won 62 games and managed to squeak past Philadelphia for the league's best record due to tiebreakers.

The Celtics's playoff run started with a first-round bye, straight into the conference semifinals. Despite the layoff, the Celtics easily swept the Artis Gilmore-led Chicago Bulls, and then faced the defending Eastern Conference champion Philadelphia 76ers for the right to advance to The Finals. After a hard-fought and physical series, the Celtics eventually came back from a three-games-to-one deficit to defeat the Sixers, repeating a feat they accomplished in 1968. Five of the games in the series ended with the winning team on top by two points or less, including a 91-90 nail-biter in Game 7.

Both teams had met in the playoffs the year earlier, when the Rockets were in their final season in the Eastern Conference. The 1980 Eastern Conference Semifinal matchup had a slightly different Celtics team, with Hall of Fame center Dave Cowens still playing for the team, as well not featuring perennial stars Kevin McHale and Robert Parish, both of whom would not arrive in Boston until the 1981 season. Rick Barry for Houston was also in the final season of his career in 1980. The Celtics blew out the Rockets in a four-game sweep, by a total of 74 points in the 1980 Eastern Conference Semis.^[2]

Road to the Finals

(*)The Celtics were tied with the Philadelphia 76ers for the NBA's best record, but the Celtics earned the division title and the overall top seed based on tie-breakers.

Regular season series

The Boston Celtics won both games in the regular season series:

Game 1

No one figured this series to be much of a Finals. Houston, in fact, had lost its previous dozen games to the Celtics, including a 4–0 series sweep in the previous years' playoffs. But Malone, who had averaged nearly 28 points and 15 rebounds over the season, would have none of the "Boston Curse". He came into the series fired up, going so far as to call the Celtics "chumps". The Celtics, meanwhile, were coming off three close games in the Eastern Conference Finals in upsetting the heavily favored Philadelphia 76ers. So, the Celtics were understandably flat.

Houston led 57–51 at the half and kept that intensity through the game. Late in the fourth period, with the Celtics trailing 87–84, Bird put up an 18-footer from the right side. As soon as he turned it loose, he immediately rushed in for the rebound. He caught the ball in midair as his momentum was carrying him out of bounds on the baseline just right of the lane. In an instant, he switched the ball to his left hand (a right-handed shot would have hit the side of the backboard) and flipped it in the basket. Bird would finish with 18 points, 21 rebounds, and nine assists. Moses Malone would grab 15 rebounds, but was held to 13 points.

The crowd went nuts over Bird's shot, with general manager Red Auerbach leading the cheers. Bill Russell, who was broadcasting the game for CBS, looked on in disbelief.

"Larry was able to make the play", said Russell, "because he not only knew where the ball was going to land, he knew that he knew."

The shot carried Boston to a 98–95 win and Auerbach proclaimed, "It was one of the best shots I've ever seen a player make."

Game 2

Malone would come up big in this game, scoring 31 points and pulling down another 15 boards. Bill Willoughby would add 14 off the bench to make up for poor shooting by Robert Reid (0 for 7) and Calvin Murphy (4 for 13). Reserve guard Allen Leavell's late basket would give the Rockets the 92–90 victory. Bird would lead the Celtics once again with 19 points and 21 rebounds. The victory was Houston's eighth road win of the playoffs, a record that stood until the 1995 Rockets won nine playoff games en route to winning the championship.

Game 3

With the series back in Houston, Robert Reid, matched up with Larry Bird, would begin to garner attention for his defense on the Celtics star, holding him to three baskets and eight points. But, the Celtics would not need Bird's scoring in this one. The Rockets shot a paltry 3 for 17 in the second quarter, fell behind by 17, and never recovered.

Cedric Maxwell led six Celtics in double figures with 19 points. His teammates, meanwhile, played some pretty good defense of their own, holding the Rockets to 71 points, the lowest output for an NBA team in a Finals game since the Syracuse Nationals scored 71 in the 1955 NBA Finals (which was, incidentally, the year the shot clock was introduced). The record low stood until it was embarrassingly shattered by the Utah Jazz in Game 3 of the 1998 Finals when they lost 96–54 to Chicago Bulls.

Game 4

Reid continued his air-tight defense on Bird, holding him to another eight points, while scoring 19 himself. The star of this game was Mike Dunleavy, Sr., who had 28 points. Malone would add 24 points and 22 rebounds as the Rockets tied the series. Another key was the Rockets' relentless offensive rebounding and second-chance opportunities; they grabbed 28 offensive rebounds (Reid had 10 and Malone nine with four put-back dunks) on the way to out-shooting the Celtics in attempts, 103 to 74.

Game 5

The Rockets had a losing regular season record at 40–42, but, up to Game 5, they showed they definitely belonged in the finals with the Celtics. So, no one could blame Moses Malone for doing some trash-talking. Earlier, he had simply declared, "Boston ain't that good." Before Game 5, though, Malone went a little too far, saying, "I could get four guys off the street in Petersburg (Virginia, Malone's hometown) and beat them." This was all coach Bill Fitch would need to motivate his troops.

With Bird still struggling offensively, Cedric Maxwell shouldered the load, scoring 28 points and pulling down 15 rebounds and sparking several fast breaks to a Celtics rout, 109–80.

The infamous on-air incident between Rick Barry and Bill Russell occurred early in the third quarter of this game.^[3]

Game 6

Motivated from Malone's previous barbs, the Celtics took it right to the Rockets back at The Summit, leading 84–67 in the final period. However, as coach Fitch looked on in disgust, the Celtics went five minutes without a basket as the Rockets, led by Calvin Garrett, reeled off 13 unanswered points in a furious comeback and eventually cut the lead to only three, with the Houston crowd erupting louder after each basket. Larry Bird then finally broke out of his shooting doldrums to personally blunt the Rockets' rally. Bird hit a 15-foot jumper, fed series MVP Maxwell for a basket, and hit a back-breaking, 24-foot, three-point shot to put the Rockets away for good and send Boston to its 14th NBA Championship, and at last a championship ring for 11-year veteran Nate Archibald.
