If they don't sign him, they're making a huge mistake imo. Watching the video on him shows me that he's nowhere near ready to really play, but signing him to any deal would be well worth the roster spot in publicity. Problem is, we don't start playing home games until the middle of the season so if he isn't going to be around for the whole year they wouldn't get to capitalize on him that much.
I'm actually a pretty big Wizards/Sporting fan and go to a few games a year so between the new stadium, Livestrong sponsorship, and now this, I'm pretty damn excited. Not to mention they won their first game at Chivas which is a great sign.
