One thing I meant to note in my post below, but forgot: while Nigeria goalie Vincent Enyeama deserved to be Man of the Match (as did USA netminder Tim Howard), Enyeama made all his saves as a result of cheating far post. Strangely, I have not seen this commented on anywhere.
It worked! I have personally noted that Leo Messi will almost always go far post if he is shooting, and perhaps Enyeama picked up on this from watching video. However, if Enyeama keeps leaning far post, someone is going to notice and fire in an easy one on the near post.
Enyeama made some fantastically athletic saves, no matter how you look at it.
