That just goes to show how much the MLS2 teams prop up the western conference. This would be one hurdle to any USL Premier and pro/rel within USL. If you move the most likely suspects up to USL Premier the western conference would lose OKC, Las Vegas, Orange County, and San Antonio (assuming St. Louis/Sacramento/Phoenix all move to MLS). You'd then be left with a lot of MLS 2 sides in the Championship and League One. I guess you could do away with conferences at the lower levels but I don't see why you would.
