Brian Belichick is the youngest of Bill’s three children. He graduated from Trinity College in 2016, where he studied anthropology and played lacrosse for the Bantams, according to his Patriots biography. That same year, Brian joined the Patriots as a scouting assistant and was promoted to coaching assistant in 2017, where he joined his older brother Steve on the coaching staff.
In a 2018 interview with The Providence Journal, Steve shared his thoughts on working alongside Brian. “It’s definitely been different,” Steve said. “It’s good to have him on the defensive staff and work with him every day.” He added that while they had spent time together before, being able to teach Brian more “relevant things” in coaching had been rewarding. Steve also praised his brother’s intellect, calling him “really smart” and an “analytical thinker.”
