And the Contract Prediction Winner Is… You!

As I write this, the winter free agency period has essentially drawn to a close. Out of the top 50 free agents I highlighted before the offseason began, 48 have found homes — sorry, David Robertson and Kyle Gibson. Per RosterResource, only five free agents – including the two holdovers from the top 50 – accrued 1 WAR or more in 2024 and haven’t yet signed new deals. In other words, all the signing that is going to happen basically has, so it’s time to look back and see how you and I did at predicting the deals players would sign.
I like to evaluate my own predictions in service of making better ones in the future, dividing them up into a few categories. First, I break signings down by position, because the market for relievers and second basemen is different. Second, I look at both average annual value and total guarantee. There’s no set ratio for how to relate those two, so looking at each independently seems best to me. Finally, I look at both the individual predictions (how close to the actual contract that a player signed my predictions came), as well as the overall trend (how my aggregate predictions for each position group did compared to the total amount they received).
This year, I made all of that back-checking more rigorous. I put all of my predictions, as well as every crowdsourced one, into a giant spreadsheet. I noted all the contracts that were signed, made adjustments for deferrals, and ignored non-guaranteed money. I compared each actual contract to our predictions. I also gathered some of the best non-FanGraphs predictions I could find, looking to outlets like ESPN, The Athletic, and MLB Trade Rumors. Below, you’ll find how both the crowd (you) and I did, as well as the best non-FanGraphs entrant in each category. Read the rest of this entry »
