According to the Boston Globe, Patriots' tight end coach Pete Mangurian has decided to not return to the team, instead opting to join Tampa Bay under their new head coach.

Mangurian becomes the fourth coach to leave New England this offseason with this. The Globe believes his decision to leave could be as a result of Bill Belichick not giving him any playcalling duties despite his experience, opting to call the plays himself along with quarterback's coach Bill O'Brien.

Because of all the coaches now gone, the Patriots will likely be forced to hire some outside help to come in. An offseason like this is now at all rare for Belichick's staff; with New England's great success, other organizations raid not only his coaches, but also the Pats' front office (see Pioli, Scott). Although many of Belichick's assistans have failed in both the pro and collegiate levels, it really is a testament to the vast amount of repect and admiration the Patriots get, obviously warranted because of the three rings earned.
