Marge's victory was rather pyrrhic in nature. In the early years she was able to live off of Bob Howsam's rebuilding of the farm system. But during her drive to get a World Series, she destroyed that farm system to the degree that Jim Bowden pretty much relied on smoke and mirrors (and getting lucky gambling on pitching rehab projects) to keep the team competitive into the 90s. And lets not forget such brilliant moves as letting Davey Johnson go (I've heard rumors it was because he lived with his wife before they were married) in favor of Ray Knight (rumored to be because she liked his wife, Nancy Lopez).
I'd say the success of the franchise during her reign was more a tribute to the baseball minds working within the skewed financial structure she mandated. Sure she'd let them go out and make a trade for a pitcher at the trade deadline if the team was close, but what good would that do when she wasn't putting any money into scouting and development? I imagine they could have won a few more WS if Marge hadn't starved the farm system of cash and chased off the system's top talent evaluators, coaches and minor league instructors. Team Clark, who knows a thing or two, has said that the Reds' philosophy at the farm level is to give the job to the lowest bidder. I think that philosophy started with one Marge Unnewehr Schott. Couple that with her behavior when the ballot initiative for the new stadiums came up and it's likely that, had MLB not forced her out, we could be looking at the Charlotte/Las Vegas/Portland Reds.
In my mind, Marge's statement about scouts, something to the effect of "All they do is get paid to watch ballgames," is right up there with "I'd rather have hustle than home runs" as a sign that someone doesn't have a complete grasp on what it takes to run a successful ball club in the long run.
