Different: The Patriots are hungrier
Tom Brady and Bill Belichick are used to winning, but they went through an uncommon drought in their last few postseasons, failing to win a playoff game in 2009, 2010, and 2011 after that Super Bowl loss to the Giants. This one's intangible and therefore unmeasurable, but both Brady and Belichick are two of the fiercest competitors in their sport. They're also close to their fourth Super Bowl rings, which would put them in the discussion for the best quarterback and coach all-time, respectively. The motivation is certainly there.
