- Total value estimates (in runs) for every MLB position player, based on hitting, fielding, and their position.
- Fielding measures are based on the average runs saved according to zone rating and revised zone rating.
- Pitchers are listed according to RAR (base runs saved above replacement) and FIP-Runs (a defense-independent pitch stat estimating runs saved above repalcement).
- League differences are taken into account.
- Closers get a leverage-based bonus (though it's admittedly rough).
