the calls that refs make, especially in wrestling, are mainly judgement calls. he/she may see something totally different than what we see sitting on the bench or in the bleachers.
i agree, there are some officials that i wonder about, but everyone has a bad day now and then.
also, we need to look at their calls from a neutral position. do we consider a close call that is not in our favor a bad call?? what if it was in our favor, how would we see it??
like someone already said, being a ref is not an easy job
