I'm not sure the Belichick vs. Brady argument will ever die a natural death, but here's an interesting look at the Belichick-Brady dynamic.
There is an undercurrent of thought that the pair were ideally suited to creating a dynasty. The two created an insurmountable opponent, they managed to dominate the NFL for two decades.
However, that's about to change: "Brady’s pewter-clad arrival at Gillette Stadium, the place where he won 20 playoff games and raised six Super Bowl banners, will provide a visceral reminder of the biggest decision Belichick got wrong."
Ultimately, the author assumes Brady will win Sunday's game, and pins the blame on Belichick for letting Brady go too early and for placing his need for "legacy" and "hierarchy" over the continued success of the team (i.e. Brady's ability to attract high-profile free agents).
