Here's what I'm thinking for alignment, pending Robin's selection:
NL East: Expos, Phillies, Mets, Marlins
NL Central: Cardinals, Braves, Pirates, Reds
NL West: Dodgers, Giants, Astros, TBD
AL East: Yankees, Red Sox, Blue Jays, Orioles
AL Central: Twins, Indians, Brewers, Tigers
AL West: Angels, Athletics, Mariners, Royals
If Robin picks the Padres or Rockies, they'll slot into the NL West. If he takes the Cubs, they'd go to the central and I'd likely bump the Reds out west since they were in the NL West from 1969-93. If he takes an AL team, I'd bump the Brewers back over to the NL and adjust elsewhere as needed.
