I have no doubt he is performing to his current ability. I have also no doubt most tall, massive forwards play their best footy closer to 27 than to 24 and if not his ability, then at least his performance will improve over the next 3 years.
Even though he played less AFL games this year, I saw some signs of improvement this year.
Where the jury is out on Tabs is his mental space. He seems to have such a placid personaility. Cant really change personality I suppose but Id just like to see the penny drop in his brain that he is a massive, strong, tall, heavy, aerobic animal, put your shoulders back, strut the Tex Walker and take some Dermott Brereton arrogance pills and get serious. Needs to spend more time with Subes.
