Tom Brady would be nothing without Bill Belichick. Before Belichick's tutelage, Brady was a sixth-round draft pick who had to battle for a starting spot all the way up through his senior yeat at Michigan.
Then again, Belichick would be nothing without Brady. Belichick was 36-44 in five seasons in Cleveland until Brady jogged onto the field and led the Patriots to their first of three Super Bowl victories.
It's difficult to say whether the quarterback or the coach deserves most of the credit for the Patriots' rise to glory, but the pairing has worked out for Pats fans.
