Good point. But I think it starts at the bottom and works it's way up. The decision to hire this guy was made by Coach Dorell and approved by the UCLA administration. I am not sure how many other schools would be willing to hire someone with a crimminal record, but I am certain that the NCAA should not be investigating the backgrounds of every staff member hired into all athletic programs. That would be a monumental undertaking.
Perhaps there are extenuating circumstances that Coach Dorrell is aware of that has not come to light. But then when faced with what he is, I guess lowering your standards is to be expected.
