I'm of the belief that success/failure is irrelevant. It's the playing time and coaches that matter. And, of course, training budget. As a commish, I've never been "MAINTAIN YOUR MINORS!!!" I feel, if you want to give my guys 23 AB over a 3 game series, you're helping me develop my players. That said, owners who don't maintain their minors generally leave a mess when they leave and/or miss the MWR.
