Do you think it could have been a combination of the USA being less aggressive and Jamaica pushing the attack considerably more after the goal? That looked like the case to me. If so, then Jamaica partially screwed themselves by playing so many dudes behind the ball early on. Not that I am complaining. From the time of the goal until about the 86th minute when all organization fell to pieces, Jamaica were making me plenty nervous.
That being said, the first 2/3 of that match was an impressive display by Klinsmann's side, especially so given they were missing key personnel.
