Impact of Brady's new deal

In a move that will be cursed by representation for Joe Flacco, Tony Romo and Matt Ryan, Tom Brady has inked a three-year extension to stay with the New England Patriots through the 2017 season (when he'll be 40 years old) at a rate of just $27 million for the entire span of the deal. Brady is certainly leaving some money on the table here, but he does have the luxury of giving the Pats a discount, given the earning power of his betrothed. So what does the deal mean in a larger sense for the Patriots?
