White football players just aren't fast enough... and the ones that are, aren't tough enough.
Just like black quarterbacks aren't smart enough to make quick decisions, at least not quick/smart decisions, which ends up resulting in piss poor NFL quarterbacks.
Example: Steve Mcnair during the superbowl. He felt pressured, and instead of throwing the ball into the endzone, he didn't process the info as fast as, let's say, a Kurt Warner, so he scrambled, and made a quick decision, by throwing the ball 5 yards short, forcing his WR to try making up for his mistake against one of the faster defenses that season. If roles had been reversed, Kurt Warner would have thrown the ball into the endzone. Perhaps it would have been dropped or picked, but Warner would have put his team into better position to tie that game. Why? Because what Warner lacks in athletism, he makes up for with football intelligence.
None of us actually want a black quarterback leading our team. It's not because we're racist, it's because black quarterbacks are some of the most ignorant athletes in sports. I repeat, black QUARTERBACKS. Am I saying black people are stupid in general? Not at all. I know many intelligent black people. I also know a few intelligent black athletes, just not intelligent enough to play the quarterback position.
That's life.
