I believe it is even more important for us to complain about not getting the 50/50 calls when we win the game. That way we can't be accused of blaming a loss on the refs. We won despite them, which shouldn't at any time stop us from complaining.
The fact is the Sharks were expected to win, and win comfortably, so the refs naturally look for reasons why they aren't winning. For example find penalties for them were none exist, after all we must be cheating to be winning. Disallow our tries because they don't think we are good enough to score them. Allowing their tries because they believe that they are good enough to score them. It's simple expectation bias, of course it's unconscious bias, but that doesn't mean it isn't real and affects us.
