No... a real apology rather than one where he still tries to blame (if you will) the opposition for his actions would suffice.
Y'know... there's a reason people "jump all over Australia" when it comes to their disciplinary infractions. There is, I believe, a sporting culture in Australia that is quite negative. Throughout all age levels, all abilities of cricket (or sport in general), there is an aura of sport being much more than just enjoyment - that, I believe, is not a good thing. To use myself as an example, in high school, I was a somewhat talented batsman (not that good, but enough to get more than a few games in the 2nd team or so) - however, playing cricket and sport in general for an organised team (in this case, a school team) was simply not enjoyable. It seems to me that many Australians take sport much too seriously - a simple misfield is met with abuse, a poor throw the same...even the whole culture of sledging, and how it is almost seen as a good thing! To me, it speaks of a nation that is searching for an identity, and is finding it only in sport - thus, you take it too seriously and become unlikeable as a result. People aren't finding fault with Australia for no reason, it's a result of a sporting culture that has sucked the fun out of the game. You may call it passion, but I think it is something far worse.
edit: I'm sure I'll have people jumping on me for this post, calling me racist and whatnot. That is not the case, whatever you may believe.
