I agree that the Denver loss shouldn't rest on Romo's shoulders alone. But he isn't a Super Bowl winning QB. He can make some incredibly bone-headed moves.
He played a magnificent game for 3 and 3/4 quarters. One of the best I've ever seen from any quarterback. The guy was dropping balls in buckets. But for some reason, when a game is on the line in the most crucial moments in the 4th quarter or overtime, he makes huge mistakes. I respect him though because at the podium he basically said it doesn't matter what he did (500 yards passing 5 TD's) because they lost.
