I doubt anyone would think the refereeing would be improved just because they were only doing BE games.
Fans always have seen Refs as incompetent because they only really notice the mistakes.....and personalities of some will always rub fans and coaches the wrong way.
Mistakes would still happen and personalities would still rub people the wrong way........Not sure how the NCAA grades refs but maybe that is part of the problem.
I think it is just a tough job and these guys eventually forget over time that nobody is there to see them......
