Utah sports a team that is roughly 1/3 white, 1/3 black, 1/3 poly.

Williams, Williams and Allen are black
Pita, Tevi and Asiata are poly
JJ and Bolles are white

You could argue the next Ute off the board would have been Dimick (white).

In other words, Utah's draftees directly reflected their team makeup.

If you go back to 2010, Utah has had 8 white guys drafted, 11 black guys, and 7 polys.

Looking at Utah's current leaders, it's more of the same. If it was only black guys getting drafted, it would validate your point. As it stands, BYU should still be sending white guys and Polynesians into the league.
