I know fans of the Dbacks, Reds, and all ten of the D-Ray fans will be mad. But imagine a Premier league. With just twenty teams. I think this idea would not only improve MLB but AAA. You could Expand the PCL and IL to 20 teams each. That way all MLB teams would have two AAA teams, places like Pittsburgh playing Buffalo, Indy, Lousville playing Kansas City and Milwaukee.
Imagine 250 of today's current major leagues playing in AAA.
