This is a phenomenon that doesn't stop with former Patriots assistants. Almost none of the players New England has jettisoned since the Belichick regime started in 2000 have had a greater impact elsewhere.
Drew Bledsoe, Lawyer Milloy, Ty Law, Terry Glenn, Deion Branch, David Givens, Tully Banta-Cain, Tom Ashworth, Adam Vinatieri, David Patten, Damien Woody, Joe Andruzzi, Willie McGinest, Tebucky Jones, Marc Edwards and Daniel Graham were all cut, traded or signed elsewhere as free agents. None of them were better off elsewhere.
Just a little something for you to chew on.
