I think in NE they run the football team like fortune500 business.
There is accountability throughout the entire organization... the ENTIRE organization. Every coach, player, scout, administrative personnel has clear expectations. I feel like other teams hire 'football' guys who; sure they may know the game well, but in NE they fill their organization at all levels with people who have that corporate style mentality.
In reality there is no difference between how successful football organization vs any other successful business.
Talent is talent.... every NFL roster is filled with it which is why on any given Sunday, for the most part anybody can beat anybody.
