Guess I'll break down these round of 16 matches a little bit.
Mexico- Netherlands
I've been impressed with the Dutch thus far. Although Mexico's goalie has been terrific, I think the Dutch break through and take this one. Look for them to go pretty far as the draw sets up nicely for them and Argentina to meet in the semis.
Costa Rica - Greece
The Ticos have been one of the surprises of the tournament. It was posted earlier, but the Greeks are tough to watch with their style of play. I am picking Costa Rica to get through this one.
France- Nigeria
The French have been strong and seem to be continuing their pattern of one good World cup followed by one bad one. This year is their turn for a good one. Although, I think the Germans stop them in the quarters. Nigeria hasn't been impressive at all in this World Cup IMO. I see this as a mismatch
Germany-Algeria
This is probably the biggest mismatch of the round. Germany should advance without problems.
Argentina-Switzerland
The Swiss have been unimpressive and their defense has been shaky. Argentina should roll.
USA - Belgium
Belgium hasn't been impressive in this tournament. But, I think they are far more creative and talented on offense than the Americans. I have to go with Belgium here.
Anyone thinks US has a chance against Belgium ? Belgium has some very creative players who can unlock decent defenses and USA has a disciplined defense - but not a dominant one and also the US does not seem capable of playing possession football for long periods of time. Need the USA offense to be clinical and for the defense to be over cautious.
Of course the Americans are capable on winning. Belgium hasn't played up to potential thus far and is a far easier draw than someone like the Germans or Argentina. There is some reason for optimism. But, I picked Belgium to win for a couple of the reasons that you stated. The Americans are really lacking in passing and creativity. It is going to be hard for them to score against better opponents unless there is a giveaway of some sort.
