Want to see what a player’s future trade value will be? Or estimate his free agent or extension contract? You can play around with all kinds of scenarios here if you’re a GM-level subscriber.

Click on the tabs for each scenario. Here's a video showing how the future trade value tab works. And for free agents and extension candidates, use the dropdown to see how the contract would vary by changing the number of years.

Front Office-level subscribers and above can also see a history of past and present trade values. We also visually display our calculations, so you can see the surplus-value gap between field value and salary in each scenario (except for prospects, who have only implied surplus value). And there's a special subscriber-only comment section below each player's data, so you can have an exclusive conversation with other subscribers.

To give you an idea how it works, we’ll always show a featured player for free.

Let’s get Jarren Duran locked up and extended. The Red Sox should buy out his 4 arb years and add on a few more. I think the Red Sox should consider buying out 27yr old Jarren Duran’s 4 arbitration years and tack on 2 more years with a 7th year team option or a $5m buy-out with a $5m signing bonus for a guaranteed $80m 6yr deal for ages 28 through 33, (‘25 - $5m signing bonus + $5m, ‘26 - $7.5m, ‘27 - $10m, ‘28 - $12.5m, ‘29 - $15m, ‘30 - $20m, ‘31 - $20- team option or a $5m buy-out).
