The New England Patriots added 13 new players on defense compared to just four on offense.

Bill Belichick had slowed morphed the Patriots from a defensive-minded team into one that relied on shootouts led by the passing game of Tom Brady.

The Patriots have replaced their 3-4 defense in favor of a four-man front that features two hybrid defensive ends/outside linebackers with two big tackles in the middle, supported by three linebackers.
