So the Commish says of the number of clubs in the league; "we could have quite a few more than that ." Which, of course, begs the question: what fresh hell is this that is brewing in the devilish minds at MLS HQ? After a few years of subtle shifts towards a more traditional league format, "quite a few more" than 18 suggests to me that we're staring down the barrel of an NFL style conference/division geographic ghettoization.
But what about the intriguing alternatives?
(1) The Euro-queer, Pinko version of MLS could feature the holy grail of Eurosnobbery--the addition of promotion and relegation, with the limitation (hello investors!) that clubs would never be relegated from the league itself, only bounce back and forth between the top tier (MLS1) and the lower division(s) (MLS2, MLS 3, ad nauseam). In fact, this might be where MLS Cup could start to make sense--as an actual "league" cup, running in parallel with the Open Cup and the MLS single-table divisions. So you could have an MLS champion (the top points total of the MLS1 season) and have MLS Cup, involving all of the teams from various divisions (seeded of course), which extends past the end of the season in lieu of an actual playoff format.
(2) El Em-ay Ell-ay Ess-ay Latino could fuse the Brazilian state system with an Apertura/Clausura tournament structure. To whit, have the Apertura portion of the season feature regional leagues (Great Lakes, Mid Atlantic, Northwest, etc.) that serve not just as tournaments in their own right, but also as qualifiers for the nationwide tiered Clausura (the MLS1, MLS2 structure mentioned above). And, to satisfy the unquenchable American thirst for playoffs, the regional leagues could also feed a national Apertura playoff featuring the winners of the regional leagues, giving you a national Apertura and Clausura champion, who would then, presumably, be pitted in a winner-take-all gladiatorial fight to the death in the Coliseum or some such nonsense ;-). This format also gives you the added benefit of Summer and Winter breaks that could have somewhat staggered starts/finishes in order to account for the wide variety of climates across the US and Canada.
So what do you think, dear readers. Are we headed for a brave new Euro-Latin world, or will Garber and his minions try to shoehorn MLS into a more "American" (break out the lapel pins!) league format?
