I can't comment on your opinion regarding the hiring of the head basketball coach at UAB because I'm not familiar with the situation. I will say that if they didn't consider all candidates, regardless of race, they were wrong.
As to your other comment about the NFL unevenly promoting Black QBs, I think that's nonsense. Yes, the NFL is a business and that business sells an entertainment product. I think your argument falls down in a couple of places. First, I don't think the NFL cares whether your QB stands like a statue or runs like the wind. All they care about it is putting a quality product on the field that fans, ALL FANS, enjoy. When Mike Vick had his heyday in Atlanta, there were just as many white guys walking around in Vick jerseys as black guys. Same thing with RGIII last year. Fans like a winner, regardless of race. Second, I look at the crop of college QBs coming out, and there is no dilineation between them as far as style of play and race. In this year's draft, Teddy Bridgewater is regarded as the brightest pocket passer and the most athletically gifted passer coming out is Johnny Manziel. I think the race barrier for QBs has been totally broken.
If you want to see a real example of discrimination, look no further than the CB position. Where's the next Jason Sehorn?
