Disagree that it's unpopular. I think most would agree with you because it's a fact.
That aside, I don't think they're "over recruiting" a demographic. I think it's probably quite silly to boil it down to race and decide you have to recruit more or less of a group. They're getting the best they can regardless. That's been evident. A lot of Poly's will fit that interior DL position, but at DE we've seen potential candidates like Batty, white, Baker, white, Daley, white, Albright, white, Schoonover, black, Hanna, black.
There will continue to be really good Poly DE candidates and others as well. BYU should and will try for the best they can get.
