Retrospectively, I don't know why Mexico CT'd vs. Canada but not against us, in light of the fact that now they're unlikely to win another game.
I had to think long and hard about this one. I basically think Mexico was out to screw the "gringos". That's the only explanation I can see. They played normal against you because they wanted to save the CT for us, but still maximize the point differential for the other teams in the round. I'm not impressed and I will be watching their last two games with great interest.
