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 hired McMillan in 2021 as a defensive assistant where he primarily worked with Titans outside linebackers. In 2022, he worked as a defensive line assistant coach alongside Williams, who was named the Patriots defensive coordinator. McMillan continued to work with Titans defensive lineman in 2023.
