Lots of very good soccer matches start very slow and get good progressively, at a steady rate. Sometimes, there's a big moment that turns things around. That big moment could still come, but we're beginning to approach the point in the match where we're allowed to declare it crappy.
The United States and Mexico haven't done very much through 28 minutes of play, for various reasons. Both teams are lacking their best players, and both have guys playing out of position. Additionally, most of these players were involved in competitive club games last weekend, and all of them except for Maurice Edu will be involved in competitive club matches this weekend.
There's a lot of standing around. The movement off the ball has been poor from everyone. The United States is content to put a lot of guys behind the ball and Mexico isn't interested in getting risky and creative in an attempt to break them down.
A stunning goal or a bad tackle that pisses everyone off could turn things around, but we're pretty close to being able to declare this match as lame.
