mark b., welcome to Caste Football! I think the main reason is the media, who has been largely responsible for propogating the myth of black athletic supremacy. I think it points to a desire by those in control of the media to make the white male the personification of all things bad, and an inferior person. If they can make us think we are not as good as we are, then they have gone a long way toward changing the society. This is also one of their goals, They don't want to see whites dominate anything, hence the effiminant, dumb, fat, or lazy portrayals of whites in the mainstream media. Sports is the perfect format for them to use to make white men feel inferior. Through their early efforst to make the black male "better athletes" they have influenced at least 2 generations of coaches and recruiters into believing the lie. This is how the Caste System exists in its current form. Thankfully, whites from Europe are proving the myth to be just that. Whites now dominate boxing again, we have always owned 98% of all Olymic sports, weightlifting and strength contests, international basketball competitions, baseball, and even after 35 years of the Caste System in college football and the 70%+ black NFL, you can still say we have an extraordinary amount of talent and skill that often dominate the positions they are still "allowed" to play in. No matter how hard they try, whites will still prove themselves champions time after time!
