Not that I am aware of and there probably shouldn't be. Every position player on my team ranks fairly low in the league because my pitchers get a lot of strikeouts, and that only helps the catchers RF. Also, my outfielders hardly get any balls because I focus on groundball pitchers and not flyball pitchers.

In other words every team is different and you really can't have a standard that is accurate.

This is how I use it. I compare two guys on my own team playing the same position. For instance if you have two guys who platoon in Right Field you can compare their range factors and possibly make a decision that one guy is so much more valuable on defense that he needs to be the full time starter.

I have probably the second best defensive shortstop in the national league. Yet he's something like 25th in the majors in range factor. Range factor is a crucial stat but only if you know how to use it. If you don't you will always be comparing apples and oranges.

Say you put 7 aging catchers, who can barely walk, in the field along with one average shortstop. That shortstop would probably have a range factor of 10.25 or something because almost all of the outs would either be from him making a play or the pitcher striking a guy out. He's still nothing more than an average shortstop on a team that depends on him making a ton of plays. Put him with a good defensive team and suddenly his range factor is 5.00. That is the pure danger of the RF stat. It is totally worthless to compare it with guys on other teams. But it can be vital when making judgements about your own team.

WIS gives us a stat that I would look more closely at. +/- plays. If your guy is doing his job he won't have many minus plays. If he's doing well he will have some plus plays. And that is a true comparison with other guys in the league. If I start seeing a guy get minus plays I start thinking about getting rid of him or trying him at another position.

I hope that helped some.
