When Snyder left the first time they had a black coach who really blackened up the roster and had the goober josh freeman as his qb. I really don't think white friendly coaches seem to even exist anymore. To have a coach or program be white friendly certain academic rules and standing need to be adhered to and I can't think of many schools that actually hold their black student athletes to any academic standards.
I'd agree, although I think coaches can be a part of it; like this year, Fedora had a fairly white-friendly UNC team, something that usually would never happen. Overall, there's not many; even "prestigious" academic institutions bend over backwards to accommodate their precious affletes. There's not too many examples I can think of in college football anymore. Beilema was great at Wisconsin, now after Morgan and co. leave, he'll have just another SEC caste team, with perhaps 1-2 more white defenders and linemen than usual.
College basketball is a little better, although most of the white-friendly schools have high academics in basketball as well. The white friendly teams year after year, like Davidson, Gonzaga, Notre Dame, Butler, Wisconsin, etc. all have higher academic standards. Although as Brian Kelly showed us, that doesn't matter. I'd definitely consider guys like Mike Brey or Mark Few white-friendly coaches. Even with the academic standards, you still need to have a coach that won't bitch and moan and try to get around them.
In terms of lacking a high academic standing, there aren't many big schools that will actually recruit white guys in either sport.
