Speaking on his podcast with Julian Edelman, Rob Gronkowski relayed a time where Mike Vrabel "outplayed" Bill Belichick as head coach.

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.

Mike Vrabel joined the Patriots as head coach in a throwback to the Bill Belichick era. But his tenure won't involve Belichick's son, Brian.
