Stam just plainly didn't want to compete, that's all there is to it.
Still, we had Bouhlarouz. I'm pretty sure he was the best defender in the whole World Cup league. With him and Van De Sar in the goal, it's pretty much a miracle anyone managed to score.
Still, if there's any player I thought would have been handy in this game, it's Edgar Davids. Too bad he got such a ego and ruins all team dynamic, because he is still one of the most viciously dangerous players in the world.
