When it comes to values, rather than look at individual players I do like to perform a basic "sniff" test by position and groups with similar characteristics, such as the really old or really young.
In the default FGPoints values, my nose suggests that RPs are undervalued as a collective. For example, any league where Zach Britton is valued $3 less than Alex Wood is a league I'd enjoy.
Exactly what I mean! Those who create their own values should play with positional replacement levels to address this.
