Keep trying to justify it.
There are rules against betting on sports. You are an official at that level or at least you claim to be. You should not be betting on sports at that level. The NCAA cannot do much to a fired coach that is no longer with an NCAA school. They can penalize the school and that could be coming. I have not heard of the NCAA not holding anyone responsible for betting. Ask Mississippi State, they could easily come back some years and put Washington on some kind of probation.
