There have been 25 men to call themselves a head coach or manager of the Boston Bruins, Boston Red Sox, Boston Celtics or New England Patriots since 2000.
The lone constant? Bill Belichick.
Since being hired in January of 2000, Belichick has been the model of success for all Boston-area coaches. Though all four franchises have won at least one championship in the 21st century, the Patriots’ sustained success under Belichick is something that hasn’t been able to be replicated in New England during the two-plus decades he’s been in charge. The Red Sox have had eight managers.
