Dennis Wayne Johnson (September 18, 1954 - February 22, 2007), nicknamed "DJ", was an American professional basketball player for the National Basketball Association's (NBA) Seattle SuperSonics, Phoenix Suns and Boston Celtics and coach of the Los Angeles Clippers. He was an alumnus of Dominguez High School, Los Angeles Harbor College and Pepperdine University. A prototypical late bloomer, Johnson overcame early struggles and had a successful NBA playing career. Drafted 29th overall in 1976 by the Seattle SuperSonics

In 1,100 games, Johnson scored 15,535 points, grabbed 4,249 rebounds and gave 5,499 assists, translating to career averages of 14.1 points, 3.9 rebounds and 5.0 assists per game. Known as a defensive stalwart, he was elected into nine straight All-Defensive First or Second Teams. NBA legend George Gervin said in a podcast with journalist Bill Simmons that Johnson was the hardest defender he ever played against. Johnson is also acknowledged by the NBA as a "money player" who was clutch in decisive moments, such as scoring 32 points for his team in a Game 4 overtime victory in the 1979 NBA Finals, playing smothering defense on Magic Johnson in the 1984 NBA Finals, and converting a last-second layup in Game 5 of the 1987 Eastern Conference Finals after a Larry Bird steal.  Furthermore, Johnson is lauded by the NBA as a versatile all-around weapon who played with "contagious competitiveness" and was known for his durability: in 14 NBA seasons, he played in 1,100 of a possible 1,148 games and participated in 180 playoff games, the latter figure the 11th highest number of all time. At his retirement, Johnson was only the 11th NBA player to amass more than 15,000 points and 5,000 assists.  On December 13, 1991, the Celtics franchise retired his number 3 jersey. Johnson said he would always be a Boston Celtic, and remarked that seeing his number in the rafters gave him a "special feeling". However, Johnson did not live to see an induction into the Naismith Memorial Basketball Hall of Fame, a fact that has been a considerable point of debate with sports journalists. Bill Simmons of ESPN called his Hall of Fame snub an "ongoing injustice", stating that according to him, Joe Dumars - a Hall of Famer known for strong defense rather than spectacular scoring, like Johnson - was no better [a basketball player] than him. Colleague Ken Shouler called Johnson "one of the first guys I'd give a Hall [of Fame] pass". Contemporary Boston Celtics Hall of Fame forward Larry Bird gave Johnson ultimate praise, calling him the best teammate he ever had in his autobiography Drive, which is especially significant considering Bird's teammates included Hall of Famers Kevin McHale, Robert Parish, Bill Walton, and Tiny Archibald. On April 3, 2010, ESPN Boston reported that Johnson was posthumously elected to the Basketball Hall of Fame. This was officially confirmed two days later when the Hall released the list of 2010 inductees.  On October 26, 2007, a learning center was dedicated in Johnson's name in the Central Branch of the YMCA of Greater Boston. The center was made possible by the donations and effort of Larry Bird and M.L. Carr. Johnson's family, Danny Ainge, Carr, and members of the YMCA and local community were present for the ribbon cutting ceremony. Donna Johnson said on behalf of her husband, "If Dennis were alive he would really appreciate the thought and love the idea of the Learning Center."  The NBA D-League Coach of the Year award is named after Johnson.Answer this question using a quote from the following article:
