The WERTH point system is a way of evaluating fantasy baseball players to determine their value in a rotisserie league setting. If Mike Stanton hits 40 home runs this year, that will surely help you in the HR category but just how much will it help you? That's what this system sets out to explain. The WERTH values represent an estimation of how many points in the standings you would gain by owning a player over an average fantasy starter.
After you set your league settings in the cheatsheet here, the projected fantasy starters for that type of fantasy league is analyzed to determine what the average production in each statistic would be. Using this information, we have benchmarks to compare each player against and see how far above or below average they may be in your fantasy league.
In the picture to the right, you can see what the league average is for one fictional league type in each category as well as two player projections. At the bottom of each is the projected WERTH totals which show how many points in the standings your team would gain by owning these players. You can see that if you draft Player A then you'll gain 1.2 roto points in batting average at the end of the year (which is 2.3 more than if you drafted Player B instead). Each player projects to give you above average production (since their total WERTH value is above zero) but they each also negatively affect you in certain categories.
As the draft goes on, if you are using the cheatsheets here then you'll be able to evaluate your weaknesses much easier and understand what you might want to target based on the WERTH values for your current team.
Keep in mind that players in early rounds generally generate positive values for your team to offset the negative values you may be forced to draft in later rounds that are below average fantasy starters (they can't all be above average after all). While most systems employ a value over replacement player, this system tells you a bit more than that because it takes into account all projected starting players in your league to make a comparison to.
In the vein of naming baseball tools after players (Chone, Cairo, Pecota, etc), I aptly named this system after Jayson Werth because of the fact that we're determining player's worth and, yes, because I'm a Phillies fan and Jayson was still a Phillie when this system was created.
