I'm confused where you get the impression that this poster is acting like 'only black kids are allowed to be linemen'. Outside of quarterback, the offensive line is where you're more likely to see white players. You'll typically see black players mostly represented in the 'skill' positions (receiver, running back, linebacker, defensive back -- basically any position that relies of speed and quickness). This comes from generations of racist attitudes pushing black players to the 'athletic' positions while keeping white players for the positions that require 'intelligence', 'grit', and 'leadership'. Also, it's not just the line that suffers brain injury.
