Poor, panicked defending from Jamaica. They got themselves pressured incredibly far back and the lack of shape it caused meant there was no organisation.
As Evans receives the ball, there are six players (that’s HALF the Jamaica team) standing on the six yard line like skittles. None of them know whether to stand still or to close Evans down. As a result, he has all the time in the world to find the net through the crowd.
A fine header from Altidore, but the Jamaica defender in front of him completely misinterprets the incoming cross and should have headed it away. He appears to stop mid-cross, and doesn’t attempt to jump for the ball. Either he thought his goalkeeper was coming to claim it, or that the ball was too high.
