I honestly don't know what Belicheck's beef is with Mangini - I don't follow closely enough to care really - though it sounds like there are some personal issues buried somewhere. If it is strictly based on him taking a job with "the enemy" then, yeah, he is being a childish dope, especially since most (if not all) of the NYJ ownership/mgmt has changed hands since back when B.B. had his split with them. But, even as dopey as that would be, it's still a different situation than the one where the fans of the team that a player/coach once worked for want him to make career decisions based on what they think of the team where there's a job opening. On a side note, it always cracks me up to hear old-timey fans lauding the likes of Mantle or DiMaggio for their "loyalty" in sticking with the one team for their whole careers -- as if the fact that they were legally (illegally, actually) bound for life to one team had nothing to do with it.
