It is a fact of life that refs of all kinds in every sport in every league will make mistakes in almost every game. There will be calls that are questionable to many, and missed calls that are questionable to many.
People need to grow up and accept this very human aspect of officiating and quit bitching about it. Either that or do the job yourself.
It is rare that any individual official wants to purposely make a team win or another team lose. It is almost a sure thing that no group gets together to do so. It is so rare, if at all, that each group deserves complete benefit of the doubt. It is extremely ignorant to assume one knows the unspoken, and often unsubstantiated motives of another person for the things they do or dont do.
