Chris Kissel at our sister station, PubliCola,
mentioned [see UPDATE 2] that the three challenges the Sounders would face in Dallas were red cards, heat, and arrogance. In the end though, it was a blown offsides call that cost them a win yesterday.
UPDATE: From the comments, here’s another view of the goal that makes it look like Rocha was just barely onside. Either way, the Sounders didn’t look their best yesterday.
UPDATE 2: Chris mentions below that while he posted that up, he did not write it himself. It was written by SoundersNerd.
