The sun shone brightly over Foxboro Stadium for most of New England’s 21-11 win over Buffalo on Sunday. At least above the Patriots’ sideline. “When it rains, it rains hard,” said Bills running back Travis Henry.”And it’s raining right now for us.” The Bills outgained the Patriots, but fatal penalties kept them out of the end zone until 2:43 remained and they trailed by 11 points. Buffalo held New England to 205 net yards, but gave the Patriots less than half a field to cover on both of their touchdown drives (one of which was sustained by a pair of defensive pass interference penalties). Rookie punter Brian Moorman, whose kicking was one of the scarce bright spots through the first seven games, couldn’t handle the southern Massachussetts wind as the Bills brace for the gusty portion of their home schedule.’
