Shadow, don't get disheartened. I think part of it is just a numbers game. This years combine there was 1RB, 5 WR, and 1DB. So 7 skill positions guys who even have the chance to run that fast. I don't know the exact number but I would say over 100 black guys at those positions. There are some white guys that just don't get invited also. Max McCaffrey should have got invited and would have run low 4.4 maybe high 4.3. Sam McGuffie would have lit up the combine if given the chance. Dylan Haines should have been invited this year. He was a 3 year starter at TEXAS with 12 career interceptions! But instead they invite at a black safety from St. Francis who ran a 4.7 and tested awful. There are many more white guys that could go to the combine and test very well.
Like Don said though there are many kids though who play other sports (baseball, lacrosse, soccer) instead. Maybe the kids don't want to play football because they watch football games on TV and don't see white people like them so they pick a sport where they do see white people. Or maybe their parents push them into another sport because they don't see white people playing in the NFL so they think their kid would have a better shot at another sport.
But the Caste System is the main reason you don't see those times. In my personal life I can name many white kids who were fast and athletic who didn't play any sports at all. They just thought sports were for the blacks (especially football and basketball). That they just couldn't compete with blacks so they just don't play or don't even try. In my life I can't think of any athletic black kids who didn't play something, because they thought well they are black so they have to be good, or that its their way out.
This doesn't even count the countless amount of kids who do play and get screwed over in recruiting. Who rush for thousands of yards and all-state and players of the year but never get a sniff at a scholarship.
Just think about the poll they did on the combine on who would run faster Richard Sherman or Christian McCaffrey. Any reasonable person who has any idea would be able to watch and see that McCaffrey is faster but in their poll 100% said Richard Sherman!! Or how Julian Edelman is scrappy, slot receiver but Antonio Brown is fast, explosive and game breaker. But Edelman is actually the far better athlete and its backed up by their testing results. But if you took a poll 100% would think Brown is.
I'm not sure on how to break down the caste system. But I know the more people we educate and point out the case system too has to help.
Outstanding post.
In my own life, I loved baseball and played it at a high level and had very good hand-eye coordination and athleticism. But in high school, I drifted toward the "cool" crowd, the pot smokers and the long-hairs. Coming from a broken home and a dysfunctional family it was perhaps inevitable, or the easy way out, but something I've always regretted though I later lifted myself up by my bootstraps and put myself through law school and have done many things I'm proud of.
I've seen the same with many other White boys and men ever since -- regretting after the fact that they didn't pursue sports much more strongly, also many times academics also. The White family has been chipped at and targeted for a long time, it's the Great American Tragedy. It's heartbreaking how young White men exist in such a confused state in a society whose alien "elites" detest them and want to destroy them psychologically. The Caste System exists to keep White athletes down while artificially lifting many black athletes above and beyond what they deserve, including excusing pathological and criminal behavior when engaged in. I admire all White kids who excel at sports and academics, especially the ones who come from broken families or other difficult circumstances.
