Over the weekend, MLB commissioner Ron Manfred created quite the buzz when he was asked about possible future league expansion during the Mets vs. Mariners broadcast. According to Manfred, not only does he see expansion coming, but he thinks the league would take the opportunity afforded by expansion to geographically realign MLB's divisions. For the Atlanta Braves, that could be a massive win.
There have been a lot of half-baked division realignment proposals out there including one that The Athletic's Jim Bowden put together a couple years ago. Getting such a realignment done in a way that is fair to everyone is very tricky, especially with teams in the midwest as there are going to be some of those teams that get grouped with less than favorable division partners.
