SEATTLE — Soccer’s weird sometimes. The Seattle Sounders drew 2-2 against the visiting Vancouver Whitecaps in what looked a lot like a Concacaf Champions League match throughout much of the second half. Going into the game the Sounders were top of the Supporters’ Shield race, while the Whitecaps were at the bottom of the Western Conference tied for points with FC Dallas with 7 through 9 games. The Sounders took the lead late in the first half, but Vancouver had jumped out in front just over 10 minutes into the second half after some frustrating plays from the back line and goalkeeper Stefan Cleveland.
