Tom Brady has been the story thus far. He's played like, really, really angry and led the Patriots to touchdowns on their first two drives of the game. He missed some throws in the second quarter, but has played inspired football and his teammates have rallied around him.
Defensively, the story has been Darrelle Revis. He's shadowed AJ Green on nearly every snap and forced a fumble that the Patriots recovered on the only pass Green did catch with him in coverage.
Another big story thus far: the penalties. Jerome Bogar and his crew have been terrible thus far, calling the Patriots for multiple questionable defensive holding and personal foul penalties. However, the Patriots have made some unacceptable mental errors and will need to be more disciplined in the second half.
