Lot of comments to reply to, but ive got things to get into so i will try to get to them quickly.
1- Thank you Wassal, your post was fairly informed and was actually on topic. To address you point, yes i am aware of the bell curve, the IQ testing stuff etc, and much like the IQ testing stuff, it is clear that there are more prevelant cultural elements to explain it other than any sort of "bias" on a particular group. I am sure there are some whites who could play cornerback in the NFL, but they are more likely playing reciver, soccer, baseball, or pursuing a life outside of sports. Maybe this is what the caste system speaks of in some way, but im still skeptical of the way many of you are presenting it (as if there is some grand conspiracy against whites BY OTHER WHITES to make this happen) thank you for this link, i will give it a look before i post again.
2- Andre Rison, Lawrence Taylor, etc were all REALLY GOOD. Matt Jones was not. Yes he was learning a new postion, but he didnt do it well, and being a project, he shouldnt have been drafted in the 1st. Heins Ward, , Antwan Randle el Jerry Porter(from the raiders, might be the wrong name) and a bunch of other converts turned out great but were also drafted in 3 rounds and later. It was not discrimination. He was given 5 years to pan out, he didnt, AND he had off the field problems. I can name plenty of black players (Quincy Carter, Lawrence Phillps, Maurice Clarett) that were just as average and suffered the same fate. He had one season of 700 yards, and 2 touchdowns in like his 4th year. Sorry that is not good enough. He is a bust be realistic, it hurts your entire argument when you are this unreasonable.
3- "Hip flexibility" is the way that scouts describe what they see on football tape. You know, the most important thing in evaluation. Time and again scouts that fall in love with 40 times are burned when they ignore bad tape. White players have bad tape. These coaches see them every day in practice. They see them get burned/not get separation. They dont have the scheme that bellichek has to cover up weaknesses, so they would rather spend time developing mental aspects than physical deficiencies. Again, no one has offered up the idea that coaches would purposefully set superior white athletes aside for black ones.
4- Eric crouch was too slightly built to be a nfl running back which is why reciever seemed more logical... safety? IDK why that was an option.
5- The only valid point thus far came from Seattle fan. I definitely think there may be some smoke to the fire of big time football programs not giving white corners a chance in recruiting. That actually makes sense. Still, when they are getting the TOP recruits at the position, why would they put in too much work recruiting novelty players.
6- How many white QBs actually have had 4.5 speed in the last 15 years? Some of you guys sound just as bad as black fans defending Mike Vick.
