The culture Mike Vrabel built as the head coach in Tennessee was based on physicality and winning the line of scrimmage. That's part of how the Titans came within a game of the Super Bowl in 2019, and Vrabel is bringing that same style to the Patriots this season.
That appears to be just fine with second-year quarterback Drake Maye.
Even in today's pass-happy, up-and-down-the-field NFL, you still have to be able to control the trenches. That's something the Patriots could not do last season, especially on offense, and the result was Maye often throwing under pressure.
