In 1985, 52% of NFL players were black. That was 31 years ago with average player age of around 25 years old. That would make the average NFL player in 1985 in his mid 50's now. The numbers just don't add up. Think about this. You can probably name every single black head coaching candidate for all schools in FBS. I wonder if you could name all the white ones.
*edit - Just to note, I believe you when you say you don't see race as an issue. I just don't think you understand that the old "guys" in charge still do.
