“Does anyone have a theory on why white guys seem to dominate the offensive line positions?”
Aside from the quarterback, OLs have the most complex job on the offense, and thus have to be among the smartest players on the team.
OLs have to be big, heavy, fast AND very smart. That’s a very difficult combination to find.

Aside from blue chip QBs, the top draft picks are offensive linemen.
