I'd be in favor of moving to two leagues of four divisions of four teams each. The only thing that would be particularly important to preserve would be the truly classic "storied" rivalries of the Red Sox/Yankees, Cubs/Cards, A's/Angels, Indians/Tigers and Dodgers/Giants. Heck, bring back the Phillies/Pirates rivalry that was diminished when they split them into different divisions. AL East: Red Sox, Yankees, Orioles, Blue Jays AL West: A's, Angels, Mariners, Expansion Portland/Vegas AL North: Indians, Tigers, White Sox, Twins AL South: Rangers, Royals, Rays, Expansion Indy/Charlotte NL East: Phillies, Pirates, Mets, Nats NL North: Cubs, Cardinals, Reds, Brewers NL West: Dodgers, Giants, Rockies, Padres NL South: Braves, Marlins, Astros, D-Backs As long as we're aligning mostly according to geography instead of how good teams are right now, that would probably work just fine. If they feel the need to expand one team in each league (which they really shouldn't care, since prior to the last expansion, teams were added to the same league i.e. Marlins/Rockies), move a willing NL team to the AL, like the Astros to the AL South to fuel a rivalry with the Rangers or something.
