Actually, South Africa are the biggest chokers..

Have never won any ICC World Cup Tournament, Test Match record is quite ordinary (except for having qualified for this years's WTC Championship) and the furthest they have gone is to qualify for last year's T20 Final and then lose the game from a winning position with a great catch from SKY taking the game away from them and even before that..... choked yet again in the World Cup in England in 1999 when Herschelle Gibbs dropped the infamous catch in the semi-final at Headingley and then Steve Waugh told him....'you've just dropped the World Cup' and then went on to make a match winning century to knock them out. Highly overated team....remember when WI bowled them out for 148 in the last innings of the 1992 Test Match in Barbados when chasing 201 to win...Ambrose 6-34!!
