That seems to be the plan in action. 4 divisions - 6 teams per division, but you still play everyone in the East twice and the West once for a total of 34 matches. Top three in each division make the playoffs - the bottom two in each division play a one-off for a spot in the conference semifinals. From there, it's a simple 1st vs. 2nd but crossover match. Therefore, half of the teams will have a chance to compete in the playoffs with 4 assured of a quarterfinal place.
The only valid reason for divisions in my opinion is to play an unbalanced schedule. If the unbalanced schedule ends at the conference level, they shouldn't be further divided. A lesser concern is that there are seven "Northeast" teams, meaning one of DC United or Toronto would have to be split from their more natural geographic rivals.
I've always been a fan of ladder-style playoffs, so I would propose something like this:
Code:
1 2 Q S F
1
4 v -> x
5 v -> x
v -> x v -> x
6 2
v -> x
3
v -> Champion
1
4 v -> x
5 v -> x
v -> x v -> x
6 2
v -> x
3
Round 1 and 2 would be single-elimination games hosted by the higher seed, quarterfinals and semifinals would be home-and-home two-leg matches, and the final would be a single-elimination game played at a neutral site. I like this setup because it gives clear advantages to each finishing position within the conference, except 2nd and 3rd are treated essentially equally.
Sorry to take this thread further off topic.
