FOXBOROUGH, Mass. (AP) The secondary was supposed to be a strength for New England this season.

Cam Newton became the fourth straight quarterback to torch the Patriots for more than 300 yards on Sunday, leading Carolina to a 33-30 win over the defending Super Bowl champions (2-2), whose two losses have both come at home.
