But read the individual ones; the first is really, really worth your time.
Game 1 - Netherlands v. Brazil - Friday 7am
Brazil will win 2-0, but it won't be as exciting as everyone thinks. (I'm proud of this preview.)
Game 2 - Uruguay v. Ghana - Friday 11:30am
Uruguay should have enough to win, also 2-0. Could go the other way.
Game 3 - Argentina v. Germany - Saturday 7am
This will be an absolute corker. Wake up early. Germany could win 2-1.
Game 4 - Paraguay v. Spain - Saturday 11:30am
Spain should win, easiest of the round, 3-1.
There you have them, my picks for the quarterfinals. I went 6 and two half points out of 8 in the Round of 16; not bad at all.
