Fantasy Baseball Hub has made available a spreadsheet for your
use in 2014. Plug in your projections for a player and get the dollar
values based on Fantasy Baseball Hub's formulas.
Remember, we are not mathematicians but have developed this over
years of playing roto games. The system uses "base" values in
the "average" categories (ERA,Ratio, BAve) so a player earns
positive value by being over the base. They earn negative value by
being below the base. This is then magnified by the number of innings
pitched or at bats. Each category is also given equal roto value.
It may not be the most scientific of methods, but has worked for us.
