After the Patriots let go of Belichick and Pellegrino, Vrabel has worked quickly to bring in multiple defensive coaches. Booker coached safeties in Tennessee. The Patriots also added Kevin Richardson II, who was an assistant defensive backs coach at the University of Illinois.

Patriots head coach Mike Vrabel is adding another one of his former Titans assistants to New England's defensive coaching staff, reportedly hiring Scott Booker for an unspecified role.

Detroit Lions defensive line coach Terrell Williams is leaving his position with the franchise to become New England's new defensive coordinator under Vrabel, according to a report from ESPN's Adam Schefter.
