Management realized that they screwed up drafting Rosen and decided to replace Wilks with a guy who not only had a losing record at his alma mater, but wans't even head a college head coach at the time he was hired.
Finding a coach is hard, and at the time, a solid case can be made for most candidates. (Except Urban Meyer, great coach, but who didn't know that was going to be a clown show.? And Klingler. And Saturday. . . )
But the numbers clearly show that Black coaches get screwed by management and ownership.
