Seeing you're the research tool who puts so much stock into every individual stat how about you telling me? The one individual stat by a QB that costs teams more games is turnovers.
No, don't put stock into every individual stat, because there are a lot of bad ones that have nothing to do with winning games. Use the ones that correlate most highly to wins -- passing efficiency stats like passer rating, or some form of yards per attempt. That red zone passer rating comparison of Eli and Romo in 2011 is very telling stat, because it means the Giants needed to be able to compensate for the fact that they weren't efficient passing in the red zone. The red zone rushing TD shows one of the ways they compensated -- by running the ball very effectively in that part of the field.
The Cowboys didn't have that in 2011 (and still don't, for that matter). In order to keep up with the Giants, Dallas had to maximize each red zone possession by being perfect in the passing game (Romo threw 0 red zone interceptions). Being perfect in the passing game is made even more difficult when the defense doesn't respect your running game and knows you have to pass. When you look at "Romo's" 0-1 record in the win-or-go-home game that year, just remember that if he isn't perfect in the red zone all season long, his win-or-go-home record improves to 0-0.
Romo's perfect red zone performance in 2011 is one of the reasons Dallas is the only team in NFL history to rank as low as 20th in rushing TD and defensive passer rating two consecutive years and not have a losing record either year. Dez Bryant is another reason. Jason Witten is another.
In 2011, the Giants' RB ran the ball 61 times in the red zone, scoring 16 TD. The Cowboys' RB ran the ball 59 times in the red zone, and scored 3 TD.
Give the Giants 3 TD and the Cowboys 16, and
then compare the QB. How many games do the Giants win in 2011 with 13 fewer rushing TD? Those extra TD have to come from somewhere. Eli has a 75.9 rating in the red zone. Where do those TD come from?
