And it is the best way to beat Brady. You just have to do while still defending against the run and with only occasional usually very well disguised blitzes because he is ne of the best at punishing the blitz. Very few teams can do it and maintain it because the Patriots are one of the teams at in game adjustments. Any player and any team is beatable, some are just much harder to beat than others.
Eli did not beat Brady. The Giants as a team beat the Patriots as a team. As long as people continue to judge a single player based on the performance of the entire team they will continue to be wrong. The QB is the most important player but he is only one player and he is only on the field for half the game. The QB vs QB battle argument makes even less sense we you remember they are not even on the field at the same time. The Giants defense beat the Brady offense and the Patriot defense failed to beat the Eli offense. Neither of those player play defense.
