Collectively, Rick Pitino, Jim Calhoun, and Gary Williams have won more than 2,300 games and six national championships and reached thirteen Final Fours. Before Pitino became the face of the Providence, Kentucky, and Louisville programs, before Calhoun turned UConn into a national power, and before Williams brought Maryland to its first national championship, these coaches cut their teeth in front of modest-sized crowds in college gymnasiums of Boston during the '70s and '80s. Boston Ball charts how this trio of coaches, seemingly out of nowhere, started a basketball revolution: Pitino at Boston University, Calhoun at Northeastern University, and Williams at Boston College. Toiling in relative obscurity, they ignited a renaissance of the "city game," a style of play built on fast-breaking up-tempo offense, pressure defense, and board crashing. Part of a fraternity of great coaches--including Mike Jarvis, Kevin Mackey, and Tom Davis--they unknowingly invented Boston Ball, a simultaneously old and new path to the top of college basketball. Pitino, Calhoun, and Williams took advantage of the ample coaching opportunities in "America's College Town" to craft their respective blueprints for building a winning program and turn their schools into regional powers, and these early coaching years served as their respective springboards to big-time college basketball.
