I just meant as perspective, that's it.
Here are the number you asked for. I merely took all the yards for the top 30 QB by combining their 2004 and 2005 yards.
Here it is:
1 Trent Green 8605
2 Peyton Manning 8304
3 Brett Favre 7969
4 Tom Brady 7802
5 Jake Plummer 7455
6 Jake Delhomme 7307
7 Kerry Collins 7254
8 Matt Hasselbeck 6841
9 Drew Brees 6735
10 Carson Palmer 6733
11 Aaron Brooks 6692
12 Drew Bledsoe 6571
13 Donovan McNabb 6382
14 Marc Bulger 6261
15 David Carr 6019
16 Byron Leftwich 5064
17 Ben Roethlisberger 5006
18 Kurt Warner 4767
19 Michael Vick 4725
20 Daunte Culpepper 4717
21 Eli Manning 3762
22 Vinny Testaverde 3532
23 Steve McNair 3161
24 Mark Brunell 3050
25 Joey Harrington 3047
26 Gus Frerotte 2996
27 Chad Pennington 2673
28 Brian Griese 2632
29 Kyle Boller 2559
30 Josh McCown 2511
So take it for what it is worth. Carr is middle of the pack, assuming all of these quarterbacks played the same amount of games, which we know they didn't.
Oh, and chew on this, if having a 6,000 yard quarterback over two seasons is so important, why did the Texans go 2-14 last year?
