In case you don't already know: many owners don't maintain their minor leagues, sign their draftees, or promote their players. Either through neglect, or saving money to spend on IFAs. Which leads to a scramble to hoard minor league free agents. If too many of these owners are in your world, and you already have adequate staffing in your minors, you'll end up with very little chance of signing a minor league free agent, because those other owners' depth charts are showing zeroes.
