I am a newbie too, but in 2 exhibition seasons and 7 games in a 140m league, I noticed that the best teams, based on winnng pct., usually have poor defense at several positions. Understand, that this is a small sample size, exh leagues don't play like real leagues (or so they say) and there also are good teams with good D. The winning, bad D teams are, as has been suggested, in +HR parks every time. They also feature dead ball era pitchers, as has also been suggested here. When I say poor D, however, I am not talking about an entire team of only D rated fielders. I have not witnessed anything like that in my limited play. I would offer that what I thought I knew about baseball usually doesn't apply here. Newbies like us have to learn to see this as a game, not as baseball, per se. You may have struck on a winning strategy. I notice also that within every letter grade is a variance in RRF. Taking players on the high side of that RRF number may, indeed, be the strategy du jour.
