MLS Power Rankings: No upset here

Upsets are good for the U.S. Open Cup, so Major League Soccer's difficulties this year parsing through the competition has made for a more exciting and substantial tournament.

Soccer by its nature often rewards underdogs: Cal FC's victory over Portland, given the disparity in possession and number of chances, would be impossible in any other major sport (and perhaps any “minor” sport, too), but who didn't enjoy the Thousand Oaks' club's inspirational run to the fourth round -- the Timbers and their fans aside?
