If there's one for certain, well-established disconnect regarding Romo it is the one between his detractors and the vast majority veteran QBs.
There is a very long list of Pro Bowl, HOF, and Super Bowling winning QBs that think he is outstanding. The list that think he is anything less than that is extremely short.
But I do recall McNabb at least laughing at the notion that Romo was a top 5 QB. But that's not the same question.
Just off the top of my head:
Montana, Fouts, Staubach, Aikman, Warner, Brady, Brees, Esiason, Dilfer, Favre, and others have all ginven him big props. I'm sure I'm leaving out a ton, but you get the point.
All of that does NOT mean the guy can't be criticized.
