This. There a quite a few members here who think disagreement is trolling. It's just disagreement. Rhet's entitled to his opinion and analysis, both of which I think are wrong, and those that disagree with him are faced with the challenge of showing him the error of his ways and stuff like "LOL, RBIs r teh suk" doesn't cut it.
His attempt to answer Paradisecity's question was incorrect. JD Drew's run production is limited by the ability of the other people in the lineup. If they make outs faster than he does, and most do, his opportunities are limited, at least they are relative to how many opportunities he'd have with 8 other JD Drew's in the lineup. To determine what 9 JD Drew's would do you have to look at how many RC he creates per out and multiply it by 27 (amount of outs in a game - the "clock" of baseball). Fortunately, RC/27 is a stat that they keep. His 3 year average RC/27 is 7.0.
That's pretty good. A team with 9 JD Drew's in the lineup scores 1134 runs a year. This of course assumes he plays every day. He's averaged 129 games played over the last 3 years. Adjusting the total for his playing time, 9 JD Drews score 903 runs per season.
It's really not more complicated than that Paradise. The RC is based off of years and years of team total output. So, in large part, it captures the situation dependent results you mentioned in your clarification of what you were looking for.
