This whole thing started with that 99 semi final against Australia, though. You can't possibly have known that they'd choke before it actually happened. For that matter, I believe the c word is thrown around too liberally when it comes to RSA. Every time they lose it's ostensibly down to them choking! No denying they've performed worse than they should have in ICC tournaments, but why they are singled out for criticism every single time is beyond me. Of the major sides, England and New Zealand also haven't won a WC; and they've been playing all WC's since 75 unlike RSA who started in 92. All this tosh about them not having won an ICC tournament is incorrect as well. If my fickle memory serves me correct they were the first to win the ICC Champions trophy, which I believe was then called ICC knockout trophy or some such thing.
Winning a WC is considered to be the pinnacle of sport but it isn't always down to skill or the team choking or not choking. You do need a little bit of luck as well; be it India catching the mighty West Indies on an off day in 83, Pakistan sneaking through with a crucial point because of rain after getting bowled out for 72, SL getting points for other teams not playing them in 96...the list goes on.
All that doesn't really count of course. It's the results that matter. I'm confident RSA will turn it around win the near future.
