I guess I don't pay that much attention. I think of El Trafico as a big rivalry. Lumping San Diego in makes sense geographically. But is San Jose really a rivalry with any of the other CA teams? Seems like Div 4 with POR, SEA, VAN, SJ, RSL, COL and Div 5 with LAG, LAFC, SD, HOU, DAL, AUS. That works well in my mind. That also gives you the symmetry of northeast, southeast, northwest, southwest, central.
I thought the article segment ZYanksRule posted said there would be one table. All teams from a single division could make the playoffs. Only division effect on playoffs is that the division winner would be assured a spot.Seems a bit rough that half of them won’t make the playoffs.
