The NCAA already legitimizes the individual referees with accreditation, no reason they shouldn't make impartiated referees available for a few positions on every crew. I used to know a Big 12 referee that lived south of Omaha. He had to distance himself from K State where he was an undergraduate but he also avoided Husker affiliated games because he was more a Big Red fan. But he said there are no real rules barring him from officiating games of either team. He made the comment it would be criminal to bet on football for him but not a thing wrong if he homered. Something called ethics got in his way he said. That was about ten years ago. I doubt rules have been added to fix that.
