Sadly, we're not agreeing. I've done the research. I won't get all the way into it, I hate the long-winded post, but we have all the data.
Hits, XBH, BB, etc, etc.
Errors, positive/negative plays, putouts, assists.
League averages for RF in both of the above.
It's not hard to figure out the break even point. I put together 5 seasons of data before I tried it. IIRC, in Moonlight Graham, I needed about .160-170 OPS+ from the "average" RF. And the average RF was just a tick over .700 OPS in MG.
