McNabb has been, statistically if nothing else, one of the top few quarterbacks in the NFL over the last 3 years or so.
McNabb's 3 year average: 14 starts, 2962 yards passing, 21 TD, 10 Int. 524 yards rushing, 5 TD. The NFL's fantasy football site says, "McNabb is arguably the best all-around quarterback in Fantasy Football."
To compare, Peyton Manning: 16 starts, 4248 yd pass, 29 TD, 19 Int. 140 yd rush, 2 td.
Favre: 16 starts, 3797 yd pass, 26 TD, 16 int. 79 yd rush, 0 TD.
Gannon: 16 starts, 3982 yd pass, 27 TD, 10 int. 304 yd rush, 3 TD.
What these other quarterbacks had that McNabb didn't is legitimate NFL quality starting players at the complimentary skill positions. He is not overrated.
The NFL's coaching policy is not "affirmative action" because they do not promote the hiring of lesser qualified coaches on account of race. They are simply trying to get qualified minority coaches into the pool of potential hires by exposing them to team executives. They are certainly doing nothing that might potentially cause a team to suffer in quality by hiring a less qualified candidate.
Besides, even if it were true that the coach interview policy was affirmative action, what does that have to do with the players? If the NFL is engaged in affirmative action at the quarterback position, where's the mechanism that causes teams to play less qualified players? Is it a secret conspiracy?
Besides, Rush was talking about the media. He seems to think that the Eagles play McNabb because the media wants to see him succeed. I guess they take their orders from the media.
And the media would hardly need McNabb to succeed to have a successful black quarterback. There are several excellent black quarterbacks in the league. Race is no longer a point of conversation when it comes to the position, as it was 15 or 20 years ago.
The entire thrust of Rush's comment is ridiculous. It only makes a sort of sense of you are ignorant of the facts, or if you share his view that blacks are not up to the challenge of playing quarterback in the NFL, and therefore any apparent success must be a creation of the liberal media.
