Generally it is a smart idea to do what your boss wants if you wish to remain employed.
None of the coaches (or even players) that report to Bill Belichick talk smack because he is the boss and that is what he wants. (Wes Welker was punished for making a series of foot jokes)
On the other hand, Rex Ryan encourages bravado and trash talking and his minions follow his lead.
I agree completely. Love him or hate him, Bellichick has control over his staff and players and you have to respect that. As a Fin fan I hope Philpin can bring that attitude back to Miami.
JP has already gotten rid of wife beater Merling and loud mouth Brandon Marshall. That is a good start.
