You have to look at almost the entire rest of the team before you look at Romo.
Look at the teams surrounding us in the statistical categories that most correlate to winning in the NFL.
Passer rating allowed - we are bottom five. The others? NO, OAK, PHI, KC. One team with a losing record (and only halfway decent because their QB, who also threw a ton of picks, carried them to it). The rest is the top 3 picks in the draft this upcoming season.
Passer rating - we are in the 5-10 range (9 overall) - Of those top 10 squads, only two missed the playoffs. Can we guess who they were? Again - New Orleans and Dallas. Is there anyone saying Drew Brees is New Orleans biggest problem? Would they be idiots if they were? Absolutely.
Rushing correlates less to winning but we were next to last in the league in rushing offense. The bottom 5 - oh look, it's oakland, jax and arizona with Atlanta thrown in.
It's not that Romo is perfect, he's just about last on the list of things that need fixed with this team. If you get a performance from your QB of the caliber we got from Romo this season and that NO got from Brees, you should stand a very good chance of making the playoffs. After all 80% of those teams did this season. Why didn't we? Because the rest of our team was absolutely dreadful. And if we HADN'T had Romo, with the company we are keeping statistically (teams like oakland, jacksonville, arizona, KC and philly), chances are that we would have had a top 5 pick in the draft.
Romo and Brees allowed their respective teams to achieve mediocrity - which is far better than they should have, when you look at how the rest of the team performed.
