Most other schools typically get all of the black OL... BYU never does. You're right, but even that is disappearing quite a bit.
But this year and in the future we could have 3... Kanuch, Lapuaho, Fusi (from what we've heard). Famika was good before he got hurt. We've had a few. And there are lots of good Poly OL outside of BYU.
Race doesn't matter. I want good OL recruited again. Though apparently I'm "consumed" with race. "Most" is a funny word. White olinemen are probably not even a majority anymore in all of football... yeah easily the position with the most, but probably not a majority, barely if that.... Maybe I'm just consumed with facts.... Look around college FB and the NFL.
