It seems like baseball has a quarterly tradition of talking expansion and realignment. Maybe that’s an effort to avoid talking about the juiced ball, but baseball has a long history of talking about adding new teams and changing up the divisions.
It’s rare for these things to actually happen, and that’s probably good - the sport is best off sticking with consistency for at least a reasonable amount of time. Adding teams and changing schedules and getting ownership buy-in and all that non-sense is no easy task in a sport that often lacks common sense. Getting it right is important, cause fixing it can take forever.
