That's pretty much the problem from a player development view, though: the players who need the Rookie and low-A levels to develop (and there are guys, especially late-round picks, who really make their names as prospects in those leagues) will suddenly be competing for Atlantic League-type jobs with 30-year-old AAA washouts. The 19-year-olds will just get squeezed out in that scenario.
It's the opposite. MLB teams will be quicker to drop Quad A fodder in favor of potential stars.
