Black Coaches: NFL v. College

By my count, there are currently 4 black head coaches in the NFL. That number represents 12.5% of the total positions available. Right now, there are only 2 black head coaches in NCAA Division I-A. That number represents 1.7% of the total positions available. Each school makes an isolated decision when it hires a coach, and I am not suggesting that any school should give preference to a black candidate, but the aggregate numbers suggest to me that something is fundamentally messed up.
