From the Pats team website:
COACHING
Deron Mayo enters his first season as head strength and conditioning coach and his seventh season with the New England Patriots in 2024. Mayo joined the organization in 2018 after playing linebacker for the Calgary Stampeders of the Canadian Football League for six seasons. He leads the team's year-round strength and conditioning program following attaining a master's degree in high performance sport from the University of Technology-Sydney.
Deron Mayo was hired by the Patriots as the assistant strength and conditioning coach in 2018.
So reading between the lines, he learned everything from Moses Cabrera.
If the team wanted to make a break from Cabrera, why promote his assistant?
