Since Bill Belichick took over the Patriots, and especially since they started winning Super Bowls and created what many would call the greatest dynasty in NFL history, the folks in New England seemed to do things a bit different from everybody else.
The culture within the Patriots locker room has always seemed like something other teams should work harder to emulate. Sure, every team can't have Tom Brady as the centerpiece of the roster, but there appeared to be more to it than that.
And it appeared that whatever that "more" is could be explained and broken down to pass on to other teams over time.
