I understand where you're coming from, but i think there's two major components to being a good AFL player. 1. To have the kind of professional attitude towards training and preparation that Miller has, and 2. Ability, talent, performance on the field, or whatever you want to call it...
He has the first, but the jury is seriously out on the second..
All i'm saying is that if I'm seeing a teammate, who is a leader of the club out on the field, who is spilling lace-out passes off his chest, missing targets from 10-30 metres away regularly, giving away pointless free kicks, and missing straight-forward shots on goal often, i'm not going to respect him as a 'player'...and that has ramifications, i believe, for how you perceive him as a 'leader'. I still believe that the most crucial aspect of being a leader is to 'lead by example' with your exploits.
The words, attitude towards training, and attitude off-the-field are very important, but they carry no weight if you can't back it up with actions on the field for mine..
