Things could change drastically for the New England Patriots, but it seems Mike Vrabel, alongside Terrell Williams, will implement a tried-and-true defensive plan for the team that has already been proven to work.

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.

Vrabel has a mix of experience and youth on his Patriots coaching staff, including Doug Marrone, Thomas Brown and Ashton Grant on offense.
