I agree that Denver has an awesome defense. One of the fastest and most athletic defenses I've ever seen. But obviously you can't evaluate a defense just based on points.
The Bears defense was on it's heels during the first half - but they forced turnovers and won the game in the second half. I think the Bears secondary is a 'bit' soft, but their front 7 is just incredible.
I can't wait to see the Bears and Patriots.
