The Western Conference leaders are starting to dominate in this week's Power Rankings.
May has seen several teams attempt to establish themselves as among the contenders for this year's Supporters Shield and the MLS Cup trophy. In Week 11, we finally had some teams emerge from the pack as the ones that each team must really bring their A game against when their name's next on the schedule. With these teams, they have some differences but there's really one common theme: the Western Conference is dominating this league through a third of the season. Seven of the top 10 teams in this week's Power Rankings hail from west of the Mississippi River, and most of the Eastern Conference squads can't do much but try to catch up.
