In respects to his drafting.. Belichick always went after smart and instinctive players rather than physical freaks. Tedy Bruschi, Mike Vrabel, Julian Edelman, Danny Amendola, Wes Welker etc. (I know not all of these guys were drafted by him, but it still shows you his blueprint nonetheless)
He placed more value on having a smart team rather than one full of All Stars. Of course he did have those guys too (Ty Law, Lawyer Milloy, Gronk etc) but once again, he valued smarts and instincts more than anything.
