I think the US' group (E) is pretty damn tough. Italy, Czech Rep, and Ghana. Not to mention the prize for coming in second in group E, is a date with Brazil to start the elimination round.
So i'm fairly confident we will not see the US advance as deeply into this tournament as they did in 2002

but hey, you have to beat Brazil to win, right?
Obviously Argentina's group is very difficult. England got a great draw, if they win their group, they face the 2nd place team from Germany's group - a very weak group.
