Doc Rivers doesn't 'look back' in regret for leaving the Boston Celtics
Doc Rivers left the Boston Celtics in 2013, five years after he had guided the team to its 17th championship banner. Since leaving the City of Champions, Rivers has enjoyed stops with the LA Clippers, Philadelphia 76ers and now, the Milwaukee Bucks. However, he has been unable to enjoy the same amount of success he had during his time in Boston.
