What the Essendon fans don't realise, is that they get a very good run from the umpires most weeks. Just one of those teams that gets a lot of the 50-50 calls and soft decisions in their favour, and are only penalised when it's an obvious infringement.
So on a rare day like today when some decisions don't go their way, it's unfathomable to them. Now they are collectively having a "does not compute" meltdown.
