In a well-ordered universe...
You truly and honestly believe that Tom Brady is the third best quarterback that ever lived? What's your reasoning? I'm really quite curious. And you also really believe that Troy Aikman was a better QB than Peyton Manning despite having only 5 3000 yard seasons in his career (you know.. compared to Peyton's 10 4000 yard seasons) and a TD to INT ratio of 165-141? I challenge you to put Peyton on those teams and think about how successful he would have been put in such situations. And you know he would have been just as successful - if not more. And that is why you can not judge players on team success exclusively.
Manning would have put up similar numbers as Aikman. The offense they employed was not a pass happy offense. It was a possession offense and emphasized the run. The Cowboys would get a lead and just run the ball to grind out the clock. Aikman wasn't throwing the ball downfield up 20-10 in the 4th quarter.
Aikman was one of the most accurate passers to ever play so it's not like Manning is going to improve that area. His career stats suffered due to the offense they employed and he sacrificed personal numbers for wins. Mike Martz made a comment that had he coached Aikman he'd have been a regular 4000 yard passer with 30 TDs per season. That's the difference in offensive philosophies between Turner/Zampese and Martz.
To simplify things I'd say the 90s Cowboys were like the 04-06 Chelsea side grinding out results by suffocating the opponent. Where as Manning's Colts are more like United from 98-03: your score twice, we'll score four.
