I think Vancouver are breathing a sigh of relief after the Timbers win last night. They would have been destroyed by Seattle, who've had their number all year in MLS and CCL. I think any of the 4 teams could come out of the West, although Seattle has my vote.
Also, if you want to checkout the penalty shootout from last night, here's a condensed version. Absolutely insane.
