They prove that with just one or two great players on each side of the ball, they can create a system around them that works, just as long as everyone else is competent enough to do their job and fill their role to aid them.

Don't get me wrong, Brady is a great quarterback, but all he has to do is be given enough time to throw 5 to 10 yard slants or outs and let everyone else do the work. He's extremely accurate and knows how to read a defense, so all he has to do is throw short and hope the guy catches it, because it's going to be a first down nearly every time due to the design of the play.

He's a great system quarterback, and most of that has to do with Belichick and the play calling and culture he creates around Brady. I think Belichick could go to just about any organization and create a Superbowl contender in just a few years, but I don't think Brady could go to those same teams and have the same kind of success.
