Where to start? First I don't really see the Mets, dominating the postseason, neither do the cubs or the white sox. You list the Cardinals as being a big market. As of the 2000 census St. Louis is the 18th largest metro area, hardly a large market. The twins, A's, Indians, Marlins, Dbacks, Padres have all had post season success, none of them are large markets. The Yanks have had a huge payroll advantage for all of 2000 and they haven't won 1 WS title, and last year they missed the playoffs. The Mariners had a 100M payroll and loss 100 games. The Orioles have a top 5 market and have been horrible forever. Payroll is an advantage, no doubt, but it is hardly the determining factor. The reason the pirate and the royals and even the brewers are/were bad for so long had nothing to do with market size and had eveything to do with bad managment. So yes, you are going to have a hard time convincing people that baseball has a competitive balance problem. The competitive balance would be a lot better if they instuted a salary cap of some type, but people aren't going to think baseball has to do something about it based on recent history.
