Doc Rivers
The Head Coach of the Boston Celtics from 2004 until 2013, Doc Rivers has an extensive history in the world of basketball, both as a player and as a coach. He competed with four different NBA franchises between 1983 and 1996, and has been coaching in the league since 1999.
Doc has built up a reputation as one of the most trusted coaches in the NBA during his quarter-century as a Head Coach in this league, and it is why he once again landed a gig with the Milwaukee Bucks less than a month ago. But despite his success and the fact that his only championship as a coach came during his time with the Boston Celtics, Rivers is not always looked back at fondly by fans of the team.
This is because of the way his exit took place. In May of 2011, less than three years removed from the 2008 NBA championship, Rivers signed a five-year extension with the Celtics to keep him with the franchise into the second half of the decade. When it was announced that he would be becoming the head coach of the LA Clippers in June of 2013, it appeared that Doc had gone back on his agreement to stick with this team.
What ultimately happened is that Rivers decided that he did not want to stay around in Boston for another rebuild, which is what the team was inevitably headed toward. Instead, he went to coach Blake Griffin, Chris Paul and the 'Lob City' Clippers. It is safe to say Celtics fans were happy to see Doc blow multiple series leads in the postseason during his time in Los Angeles.
