On any given matchday, it seems, Major League Soccer teams have about a 50% chance of winning their games–regardless if it is played at home, on the road, against the top team in the division or the last placed side.
Whenever a sense of order appears to have been established, something comes along that upsets the whole apple cart. Chicago, Kansas City, Columbus and now New England all had periods of apparent dominance that was undone as soon as it was identified. On the other end of the spectrum, DC United, Real Salt Lake and L.A. Galaxy looked hopelessly out of contention a few short weeks ago. Now? Not so much. Only the expansion San Jose Earthquakes are firmly entrenched in last place–but even they have had their moments and, it stands to reason, can expect several more.
The whole thing may eventually shake out, but for now there is no denying that parity is the state of affairs in MLS. Which isn’t necessarily a bad thing. Or is it?
