At kickoff, CenturyLink Field was about half full. It wasn't until about 15 minutes in that the stadium started to feel familiar. The cause: Extremely long lines to pass through security on the first day that fans were being wanded before entering the stadium.

The Seattle Sounders definitely noticed and promised to make sure this doesn't happen again.

"We're going to figure out what went wrong," Sounders GM Adrian Hanauer told a small group of reporters just a few minutes after the game. "If it was a problem, which it appears it was, we're going to fix it. As one of the owners, we're going to get it for sure dead on right before we do it again if I have anything to do with it. Anything that inconveniences our fans in a way that can be avoided, just is not going to happen."

The Sounders also issued an official apology on their website: "We apologize for any inconvenience and delays in entering the stadium for tonight's match. We did not have adequate points of entry for wanding. We completely understand your frustration."

Even before kickoff, it was readily apparent that there were problem. Twitter was full of complaining fans, many snapping pictures of lines that stretched several blocks long. On the South End, the lines reached Safeco Field. The lines were so bad that just before kickoff, many reported that wanding and other security efforts were abandoned in an effort to keep the situation from getting worse.

Despite the obvious problems, Hanauer also said it is the team's intention to improve the security measures not get rid of them.
