I’m sure some of our newer (and perhaps older!) owners are a little confused on how our FA Comp system works. I thought I’d take the time to answer any questions and explain bits and pieces.
FA Comp is based on numerous factors. The primary factor is still a player’s overall rating, which is what the old comp system was entirely based on. This is still the single largest determination of what comp a player is worth. Next, we look at performance (playing time is a factor in this as well) over the last two seasons, with the current season being weighted higher than the previous. For hitters, position is also taken into consideration, with certain positions being more valuable offensively (ie a SS with a .900 OPS is more valuable than a 1B with the same OPS) than others. Defense is only looked at as part of a player’s overall rating, due to the lack of defensive metrics in Mogul. Finally, we look at age as well. 29 years old is considered the median age and for each year younger or older than that a player receives a (small) bonus or penalty.
Under the old system, overalls for hitters and pitchers were considered to be valued the same. Changes in the way the sim engine works and our free agency market shows us that in general, pitchers are worth more than hitters for the same overall, so the FA calculations take this into account. The “default” B comp for pitchers is considered to be 87-89 overall, and A comp is 90+. For hitters, B is 89-91 overall and 92+ for A. The formula looks at the total number of players with these overalls (MLB playing time only) and calculates how many comp eligible players there would be for each grouping under the old system. The net result is the total number of potential comp players is the same, but the rankings are different based on the factors listed above.
We’ve had to make a few adjustments along the way. Originally, RPs were severely underrated, and that has mostly been corrected. Also, until this season, hitters with very few ABs (such as 150 or less) were ranked too highly. I think we’ve got it mostly fine tuned now but we’re always open to suggestions if you find a player you think is ranked incorrectly.
