i think this is an interesting question. conventional wisdom suggests that good teams (i suppose you can define that by winning percentage) will have a better red zone percentage than losing teams. after all, good teams score when they are closer to the end zone, right? but is that really true? of the top teams, the saints, patriots and texans are on that list as one may expect, but nowhere to be seen are the rams, texans, or bears. moreover, teams like the bengals, cardinals, browns, and falcons (who have not been good this year) are high on the list which is counter-intuitive suggesting that perhaps there is no correlation to red zone scoring and winning.
