The next installments describing the kind of stats that can be derived by traversing Event Data as well as Data Modeling are coming. Threads of posts on this site will be intertwined with each other.
The Chicago Cubs gave Edwin Jackson a $13/year contract for several years. I do not have enough past salary data to create a system that determines what a player should be paid. One value this rating system provides is an accurate picture of a player’s past performance so that career trends can be easily visualized. A good foundation of the past makes it possible to create a more accurate risk model to help navigate the future.
Was Edwin Jackson worth $13/year when signed in 2012? His best year was in 2009.
Note: When a player plays for several teams in a single season WAA must be added together to get a season total for season level comparison.
