The Cowboys finished first in defense last year, so they have a good defense. The Patriots defense won in 2001 20-17 isn't an offensive game. I believe Ty Law took one back, and so did McGanist so the defense won the championship. Brady isn't the best QB in the league, Culpepper is faster by a lot, he has more arm strength, and better accuracy. Brady is just on a loaded team, he's a good QB, not a great one.
