I know this is a stupid question, but I could not find the answer in the help section. What is the RF stat and why is it important?

Range Factor [RF]

 
(Putouts + Assists) x 9 divided by Defensive Innings Played

Range Factor simply stated is the number of plays MADE per game at the fielding position. It is better than Fielding Average in several respects: It can be calculated for almost any player this century and it takes into account the fielder's own ability to get to a batted ball - rewarding the more gifted players at each position. Positions can only be successfully compared to the same position on the field when using this statistic and early in the season numbers are often skewed as players chances are not yet normalized.

Read up on Bill James' work. It will help you with this game, as well as with real fantasy/rotisserie baseball.

Thanks! So then it would be safe to assume, if I need to improve my teams overall defense, then I should look for players with consistently high RF numbers?

It matters at some positions more than others. Personally, I don't look at range factor per se. I like to look at errors vs plus plays. More plus plays than errors is good.

Rather than follow the stats, you want to follow the defensive ratings for positions.

Stats like range factor can be distorted by other factors.  Pitchers GB/FB tendencies will lead to more or less chances for your infielders and outfielders.  Pitchers velocity ratings will lead to more or less strikeouts, which in turn leads to less or more balls in play and therefore less or more chances for your fielders.

In the end, defensive stats are merely a by-product of the defensive ratings modified by these other factors.

I agree with the last 2 posts, but I also look at RF. Not so much to decide who to pick up, more to help me make a decision between 2 players that are neck and neck and I'm having a hard time deciding who to start, or even more so deciding who my def specialist are...
