Thomas Sowell writes: "Having watched National Football League games for more than 50 years, I have seen hundreds of black players score touchdowns, but I have never seen one black player kick the extra point......Do those who believe in genetics think that blacks are just genetically incapable of kicking a football? 
Since there have long been black colleges with football teams, have they had to import white players to do the opening kickoff, so that the games could get underway? Or to kick the extra point after touchdowns? Apparently not. 
How about racist discrimination? Are racists so inconsistent that they are somehow able to stifle their racism when it comes to letting black players score touchdowns....With all the heated and bitter debates between those who believe in heredity and those who believe in environment as explanations of group differences in outcomes, both seem to ignore the possibility that some groups just do not want to do the same things as other groups."
