That's the rumor.
Vancouver has had a professional team for quite sometime, dating back into the old NASL days. Assuming this is true, this would be the second USL-1 to make the jump to the MLS.
If Portland gets their bid in this round (which I would hate to see since I want to see a club in St. Louis), that would make three USL-1 teams making the jump. If three teams have done it, why on earth don't we consider a promotion relegation system? Why is it only one way?
