Not totally that surprised that NE is getting thumped so far. The Patriots are an old team and somewhat overrated. The defense isn't that good and its rankings were aided by playing in a division with the Jets, Bills, and Dolphins (a bad team no matter what their record says).
I think the Patriots will make a strong push for a comeback, but Brady has never had a rocket arm like a top QB (Rodgers, Ryan, or Roethlisberger), so he's going to have to have to be on point hitting those windows.
