So I talked today to a Sounders rep, and the season ticket for next year includes 17 MLS matches, which means the Sounders won't have a home game against at least one other MLS team.  It looks like the unbalanced schedule has arrived.  Personally, I'm not pleased by this development, because I think balanced schedules make for a better league.  MLS is already has a huge quality disparity between the conferences, and going to an unbalanced schedule will only exacerbate the problem.
