Tbh I just reckon he's a been unfortunate to only have a short a test career as he did. Not just because he was probably good enough to have a lengthy and solid run in the test side, but because his distorted average is probably, ironically, going to bring him more criticism than if he just hadn't done very well. I mean, if he'd been called up, struggled and been cast off again people would in all likelihood be saying "Voges, could have been good but was unlucky to only get the chance once he was well past his best" or things along those lines, as he'd be in a far from unique situation. Now some people appear genuinely angry at him (my dad for example is absolutely fuming at the statistical fame he has achieved) as a result of the high scores he made along the way. I mean, what was he supposed to do, deliberately not score runs against WI just so his average would be a more accurate reflection of his ability?
That said, I guess he's not actually directly, personally on the receiving end of much of the criticism of him and I'd imagine he's just pleased to have had the test career that he did.
Edit: For clarity, I'm not disputing the view that his actual contribution to Australian Test success has been anything but small outside of his debut ton
