You have average NFL QB's shattering records of HOF QB's from 30 plus years ago because of rule changes and the NFL being a pass happy league. Everything is bent on perfecting the performance of QB's. Mark Sanchez had a higher career passer rating than Joe Namath with the Jets. It was a running league during Aikman's era with Emmitt and Barry Sanders leading the way. It makes no difference that Romo is 80 TD's ahead of Troy. Aikman outdistances Romo in every category during the post season. The Cowboys ROH under Jerry Jones is about players who've led his teams to championships.
The Namath/Sanchez comparison is a poor one if you limit yourself to only looking at career passer rating. While Sanchez has a better career passer rating than Namath, Sanchez does not compare well to his contemporaries with regards to seaonsal passer rating. Sanchez has never finished in the top ten in a single season for passer rating. Namath finished in the top five in passer rating 5 times during his career.
Sanchez career 74.1 passer rating is much lower than the league average of 83.5 over that same time period. Namath put up a career 65.5 rating against a league average 65.4 during his era.
Tony Romo has finished in the top ten 8 times during his career and in the top five 4 times while leading the league in passer rating last season. The only season Romo didn't have a top ten finish was in 2010 when he missed most of the season due to injury. He would have finished around 7th had he been able to qualify for that year.
Sure the league has made it easier on all QBs to produce numbers, but the good to great QBs still out produce the peers of their era. Romo has done that. Romo's career passer rating of 97.6 compares very well against the league average of 82.5 since 2006 when he became the starter. That is 18.3% higher than the league average.
Roger Staubach was 26.9% better than league average.
Danny White was13.2% better than league average.
Don Meredith was 12.7% better than league average.
Troy Aikman was 8.5% better than league average.
I love me some Troy, but according to many on this site Aikman played with the better offensive line(I agree until now), better running back(agreed), better #1 wide receiver(good debate), better tight end(I strongly disagree) and better defense(true). I think Romo has done some amazing stuff with less to work with and has represented the proud tradition of Cowboys QBs well. He is RoH worthy and 2 or 3 more great seasons will just solidify his worth.
