Relying on just YARDS for a QB is like just relying on YARDS to determine how good a defense is. It doesn't paint the WHOLE picture.
Brady had 23 TDs (10th), 13 Ints (17th), 3620 yards (6th), 317 comp (6th), 527 att (5th), 60.2% Comp (13th), 6.7 YPA (12th) and 85.9 QBR (10th) in 2003. That was not Elite. And not Top 3-4.
Players ahead of Brady that year in yards: Manning, Green, Bulger, Hasslebeck, Brad Johnson.
Players ahead of Brady that year in TDs: Favre, Manning, Hasslebeck, Johnson, Kitna, Culpepper, Green, Brooks, McNair.

Sorry, but Brady was very good that year but not ELITE at that point. Unless you wish to continue with some revisionist history.
