Why is it that right around 30% is the magic number in the NFL as far as whites are concerned? We all know the NFL has had this 30% template for a very long time with regards to white players as a percentage of the NFL, but why? That alone should be a clear indication of a caste system at work. The probability of this would just not seem to support this, given that blacks make up roughly 13 percent of the American population while whites are around 65% + depending on the definition. One would at least expect some substantial fluxuations over the years, but that is clearly not the case as far as I can tell. I did some further figuring and in 2008 the total white players on NFL rosters comes out to around 30.2 % out of 1699 players. (Please bear in mind that Math is not one my strongest fields, but I believe my calculations were fairly accurated given the haste in which I performed them.) White starters on the other hand make up around 26.4% of 704 players. If you took into consideration Kickers and Punters you come out with about 33% of white NFL Starters out of 768 players. (Even though special teams is not really a starting position) Here is where it becomes more interesting to me and speaks clearly of a caste system. Lets suppose legitimately that whites made up 30% of the 704 starting players on offense and defense in the NFL. If you also took into consideration punters and kickers, that would jump the percentage of white starters up to around 35% of 768 players. So it would seem to me that it might be obvious that white starting players in the NFL are being purposely kept below the magical 30% threshold of which number they are a total percentage of in the NFL. Perhaps, to make up for Kickers, Punters and other such positions like longsnappers. Though they are not starters per say, they are nevertheless, highly visible part of the game. I would be very interested to know how the percentages have correlated throughout this modern caste era of the NFL. This may seem out there, and maybe it is, because I am tired and it is late. I tend to ponder far out things at times like this when I can't sleep. That being said, what is so important about the magic number 30%? Why has the NFl seemingly gone to great lengths to reduce the white players in the league to this number and then strangely maintain it over the course of the modern era NFL caste system? Why 30%? What is so magical about that number? Has someone possibly done research that suggests that roughly 30% is a minimum for DWF's still maintaining interest in the sport and spending their hard earned dollars? Did the NBA come to a somewhat similar conclusion after the coal black thuggery era of the 90's and early 00's when fans began turning away from the league in droves? Now the NBA is around 25% white or so I have heard. That is not exactly 30%, but it very close. Close enough to make me wonder?
