Career wise, Romo has better completion % and YPA, Stafford has more total yards.
Don't forget thought that Romo has benefitted greatly from having a better run game and (career wise) better D. These are major factors.
Ironically, half way through this shitty season, Stafford has actually improved his comp% relative to prior years.
One of my biggest complaints is the low YPA, but to me that is as much a coaching issue as anything else. What play calls are being made and within those playcalls, what are the WR/TE/RBs routes? If everything is designed to be thrown short, then the YPA will drop.
There are a large number of factors that go into these numbers. I'm not saying Stafford is better than Romo, and if I had to choose between the two I would start Romo; however, the "Head and Shoulders" is not very accurate. Romo is not on par with Brady/Manning/Rodgers. Currently the asset and reason I'd go with Romo is years of experience, not a perception that Romo is better athletically.
I just don't put Romo as a top tier QB, sorry. The bigger differences in why Dallas has been better than Detroit are Run Game and Defense. Put Stafford on the Cowboys and Romo on the Lions, I don't think there is a dramatic outcome in those teams yearly performances.
And if it is fair to knock that Stafford is 0-2 in the playoffs, then it is fair to knock Romo for going 1-5 prior to last year's game vs Lions and now being 2-6. Romo hasn't been known for being great in the playoffs. Lions get a break on the PI non-call/picked up flag and Stafford is likely 1-3 in the playoffs while Romo is 1-6.
Romo just isn't "Head and Shoulders" above Stafford. They are far closer than what you guys are making it out to be, especially considering the huge benefit Romo has had in Run Support and Defense.
