Aren't there 2 different issues here?
1) Is he running his minors properly as a ML development pipeline?
2) Is he running his minor league teams properly as stand-alone baseball teams?
I think we should all care about (1), but (2) is an owner's own business. At any given level of a properly run minor league system, there will be anywhere between 3 and 10 important prospects; i.e., guys with at least some marginal chance of playing in the ML at some point. Does an owner have these prospects? Is he drafting with some level of care? Signing his top picks? Investing in amateur scouting of some kind? Does he make some effort to ensure promotions and playing time are handled correctly for these prospects? Does he avoid silly prospect-for-player trades? If the answer to all of these questions is "yes", then it seems to me everything else is window dressing. How the cannon fodder is managed is of no concern to competitive ballance. Maybe he's doing an experiment in player development, just to see what would happen with some cannon fodder, so he can become a better owner with his real prospects. Of course, if an owner has 0 (0) pitchers at every level, then we have to wonder where the important SP prospects are. But if he has important SP prospects at AAA, A+, and A-, but none at AA, then no one should be too concerned if he has only one SP starting every game at 0 (0) at the AA level. The $750,000 is pocket change and no one ought to get upset about that. Just my $.02 here.
