“I’m extremely humbled and very excited to be taking on this position,’’ Gaff said in a release. “BC High is a warm and welcoming community that has provided me with great opportunity for personal growth. Jon Bartlett is certainly a touch act to follow, but the squad coming up is a very fine group of young men.’’

Gaff has been BC High’s defensive coordinator the last four years. The Eagles had the second-best defense in Division 1 last fall, allowing 13.9 points per game. A 26-year veteran of the Everett police department, Gaff has 11 years of head coaching experience, including at Chelsea, Matignon, and Malden Catholic. He also served as an assistant at Tufts for three years.
