I believe that refs "push" games a certain direction sometimes, but even if that is not the case - the officiating is absolutely terrible and its getting worse as bad calls, of the game altering kind, happen far too often, and there is no recourse. There needs to be a way to challenge them.
Besides, if the refs want to push things in a certain direction, they can always not make a call and let things go. If they don't call a hold here or there, it can have the same results as a bad call.
