This week's rankings don't feature a ton of dramatic changes...until you get to the bottom half of the table. New York grabbed a huge victory, and Columbus finally got themselves into the win column, a mere eight matches into the season.

San Jose and Real Salt Lake are plummeting towards the cellar, while Los Angeles seems content to draw every time out. I bet their fans are thrilled.

Last week's rankings in parentheses

1. Chivas USA (1)

Chivas holds steady atop our power rankings with yet another victory, a 1-0 shutout over Real Salt Lake.

2. Chicago Fire (3)

Chicago still has yet to lose, but they'll need to win at a higher clip than their current 25 percent pace if they want to make an impact in the postseason.

3. DC United (2)

Two unimpressive draws lead to a slight drop for DC, but the offensive remained dangerous. Jaime Moreno is still playing at a high level, and it seems like DC just needs to figure out a solution in the back line.

4. Seattle Sounders FC (4)

Somebody finally managed to score on a full-strength Seattle squad with Kasey Keller in goal. An even bigger concern for Seattle has to be the high number of cards they are accumulating this season. Three red cards and 13 yellows will result in a few games missed through suspension.

5. Toronto FC (5)

D-Ro probably thought he had won the game with his 87th minute strike against DC. Toronto was unlucky to walk away with a draw, but they've scored in all but one match this season. They're a good bet to make the playoffs.

6. Houston Dynamo (7)

Houston is quietly and steadily accumulating points, this week with a shutout victory over FC Dallas. After a slow start to the season, Houston sits in third place in the Western Conference.

7. Colorado Rapids (6)

Colorado was not in action this week.

8. New England Revolution (10)

On paper, the draw at Chicago looks pretty decent, but the Revs were dominated for the fourth straight week. It's pretty clear that their time has passed.

9. Kansas City Wizards (8)

After giving last week's 15th-ranked team their first win of the season, Kansas City is lucky to only drop a single spot.

10. New York Red Bulls (14)

New York's offense finally came to life in a 4-1 victory over San Jose. Two goals apiece from Jorge Rojas and Juan Pablo Angel sparked the victory. Is this an aberration or a sign of things to come?

11. Columbus Crew (15)

Finally. Columbus grabbed a lead as they have done so many times this season, but this time they were able to hang on for all three points. It's still an uphill climb toward the top of the table, but the 3-2 win over Kansas City was huge.

12. Los Angeles Galaxy (12)

Los Angeles had a fairly decent week in the sense that they picked up points in both matches. Los Angeles is also having a frustrating season because through eight matches, they've got six draws. They're just treading water above San Jose and Dallas right now.

13. Real Salt Lake (9)

Real Salt Lake is 0-for-May right now. Things will only get tougher with just two of their next six games at Rio Tinto.

14. San Jose Earthquakes (11)

San Jose is in free-fall mode. They just look flat and uninspired and haven't managed to take three points home since the second match of the season, against Houston.

15. FC Dallas (13)

Apparently their lone win over Toronto was an anomaly. Eight matches played, four points taken. Ugly football, thy name is FC Dallas.
