IF ANYTHING DEFINES THIS GROUP, IT'S UNPREDICTABILITY. URUGUAY AND FRANCE ARE FORMER WORLD CUP CHAMPIONS, BUT URUGUAY HASN'T FINISHED higher than fourth since 1970, and France is not the team it was in 2006. South Africa is the weakest of Africa's representatives, but the organizing nation has always advanced. Mexico rarely plays up to World Cup expectations, but it is fielding a golden generation of players with European club experience. ¶ What's certain is that Group A will be competitive and generate a lot of offense, much to fans' delight. Consider: The French might as well not go home if they bomb out as they did at Euro 2008. Mexico must come out with guns blazing to satisfy its supporters. Uruguay, with a gifted striker like Diego Forlán, has to attack. And the home fans will not allow Bafana Bafana to shrink back in front of its goal. ¶ The opening game between South Africa and Mexico will reveal just what kind of soccer we'll see at the first World Cup on African soil. It promises to be an unforgettable month.
