As the game stands now, if anything, I would see the owners seeking to remove as much friction as they can between the Big Six teams and the pennant. As long as it is the team that draws fans and revenue versus the individual player, Baseball will privilege those teams as much as possible for the benefit of all.
The main thing that might prevent this from happening is some rule change that would highlight the individual over the team, such as the Golden At Bat, which, I could definitely see this happening before Manfred’s tenure is sunsetted. They have to find a way to delocalize the rooting in baseball in order to flatten the interest level among teams.
