I agree.
A guy like Pennington OWNED McNabb this year and yet McNabb is considered one of the best in the game where Pennington generally isn't:

Donovan McNabb
Completion Percentage: 60.4%
Yards per Reception: 6.9
Touchdowns: 23
Interceptions: 11
QB Rating: 86.4
Chad Pennington
Completion Percentage: 67.4%
Yards per Rexception: 7.7
Touchdowns: 19
Interceptions: 7
QB Rating: 97.4
A slow, weak armed QB coming to a team that was 1-15 last year blows away McNabb statistically. Including all the categories that you place value in.
That is
THE most recent data available. :D
You are correct that often too much goes into name recognition. Pro Bowl voting is indicative of this. But I don't think that is the Cowboys. Most of their "stars" are pretty young and are in their prime (30 years of age or less). Two notable exceptions being TO and Zach Thomas (whom I don't think anybody considers a "star" anymore).
