context: Prior to Johnsons 1983-84 Los Angeles Lakers season, West—who had become the Lakers general manager—traded Nixon to free Johnson from sharing the ball-handling responsibilities. Johnson that season averaged a double-double of 17.6 points and 13.1 assists, as well as 7.3 rebounds per game. The Lakers reached the 1984 NBA Finals for the third year in a row, where Johnsons 1983-84 Los Angeles Lakers season and Birds 1983-84 Boston Celtics season met for the first time in the post-season. The Lakers won the first game, and led by two points in Game 2 with 18 seconds to go, but after a layup by Gerald Henderson, Johnson failed to get a shot off before the final buzzer sounded, and the Lakers lost 124-121 in overtime. In Game 3, Johnson responded with 21 assists in a 137-104 win, but in Game 4, he again made several crucial errors late in the contest. In the final minute of the game, Johnson had the ball stolen by Celtics center Robert Parish, and then missed two free throws that could have won the game. The Celtics won Game 4 in overtime, and the teams split the next two games. In the decisive Game 7 in Boston, as the Lakers trailed by three points in the final minute, opposing point guard Dennis Johnson stole the ball from Johnson, a play that effectively ended the series. Friends Isiah Thomas and Mark Aguirre consoled him that night, talking until the morning in his Boston hotel room amidst fan celebrations on the street. During the Finals, Johnson averaged 18.0 points on .560 shooting, 13.6 assists, and 7.7 rebounds per game. Johnson later described the series as "the one championship we should have had but didnt get".
