I don't think so because that would mean that every ball the fielder couldn't get to would score a run, and they usually don't equal a run. Also, if Hicks makes a play on three balls a game, that means he misplays 1 in 9 chances. That doesn't sound like a lot, but it is, an unreasonable amount actually. Another thing, perhaps I'm wrong, but the range factor likely doesn't put different weight on which direction the fielder's range is most affecting the game. Slow-footed outfielders natuarally play back, which means they likely are missing more balls hit in front of them. While they'll fail to catch more of these balls, these only turn into singles which are much less likely to cause a run. Still, I'm guessing with most of these metrics, a missed ball played in front of the fielder isn't calculated differently than a missed ball that gets to the gap.
