The NFL says it's just in case the Phillies make the World Series, 'cause they'd host Game 4 at 8 pm EST that night. Somehow, I don't think Fox exactly put up a huge protest over Favre vs. the Packers @ Lambeau Field being moved to the national broadcast slot.
The USA aren't doing too badly in the tournament so far though. They convincingly beat Portugal, for the first half at least. They also drew with the hometowners, which is no mean feat given the INSANE support that South Korea are getting.
