Well, they wouldn't wind up on the Dodgers then, would they? I also find it hard to believe that a Japanese player would turn down generational wealth from any organization in baseball due to "culture shock" in today's MLB just because they don't play half their games in a city on the west coast. The argument about not having enough chance to win has more to do with the system I'm advocating be changed, too. The player still would have a right to negotiate with any team eligible to sign them over that 45 day period - it isn't that difficult for even large market teams to get under the luxury tax threshold consistently enough, either.
Maybe once over previous 5 years is too long a period for a team to be excluded from bidding on a posted Japanese/professional player....because using 2024-2020 seasons that list would be 14 teams. let's go with being over the luxury tax at least 3 of the previous 5 seasons....that same period would then only include the Yankees, Phillies, Braves, Dodgers, Astros, and Giants.
Even with the massive spending the Mets and Yankees have recently committed to, I think the only MLB team that finds itself in perpetual luxury tax hell with existing contracts on the books is the Dodgers (meaning they'd need to gut their current roster to get under that threshold due to longterm contracts and deferrals). They are by far and away playing by a different set of rules than anyone else in MLB - which should be obvious considering the fact they can be penciled in as a WS participant for the NL at the start of every season, and nobody in their right mind would bet against that. That HAS to change somehow for the good of the league.
