I think Im one of the few that hope that we don't go to the European style single table (no playoff system). We're north american, and I think we need to keep it our style. Just because England (and others) is doing it single table doesn't make it "the right way" or "proper". Keep it in line with all other N.A. sports leagues. This is our soccer league.
I like the East/West (north/south) divide. It adds 2 more (useless) cups or championships to the mix. They don't mean anything, but it's fun and has bragging rights. It's not like we need to have conferences, but that's how we do things HERE and im in favor of keeping it like that.
There's a lot associate to winning the Supporters shield, but it's not glamorous, and there's no hype, but it's still important...and it can still be played for whether we have conferences or not. As far as the playoff system... it's great. It's what we do here. If people would open their eyes, it's also what "they do over there". Name the 3 biggest soccer showcases... world cup, euro, champions league? All playoff style knock out. They could do a single table world cup. They could do a single table euro. but they dont!!!! They could, but it just can't compare to a knockout style playoff system.
It's up to Europe and the world to wake up and realize that what we have here, a playoff system, is great, and MLS is doing it right. They can keep your single table "thrills", I prefer my knockout playoff system.
