Terrible teams always seem to produce one spectacularly bad play that serves as a microcosm for the season. Chivas USA, in last place in MLS's Western Conference, can claim Mario de Luna's impressively boneheaded own goal as their own epic low-light.
Let's take another look at this. A Seattle Sounders forward makes a seemingly innocuous cross that wasn't within ten yards of a teammate. Thankfully for the Sounders, Mario de Luna decides to test his own goalie with a beautiful header to the back of his own net.
The greatest moment is when the camera zooms on de Muna to get his reaction to his ill-advised header. It's quite easy to read his lips.
