The Green Bay Packers edged the New England Patriots 27-24 in overtime on Sunday, but Aaron Rodgers didn't come away very impressed.

The Patriots were forced to go with third-string quarterback Bailey Zappe, a rookie, for much of the game at Lambeau Field.

"This way of winning, I don't think, is sustainable because it puts too much pressure on our defense," Rodgers said. "And obviously, I've got to play better and will play better."

Green Bay is 3-1 heading into next Sunday's game against the New York Giants in London.

"You can't be 2-2 losing to a third-string quarterback and not playing great in all three phases, so we had to have this one," Rodgers said. "That doesn't take anything away from the joy of winning, but this was one we had to have."
