628 players have changed hands often enough in real dynasty leagues for me to publish what they actually cost.
These are completed trades from public Sleeper leagues, graded at the values that were current on the day each deal happened. The number beside a name is how many real trades he appears in. A player is only listed once there are at least 50 of them, because below that a page would be guessing.
Pairs of players who have genuinely been swapped for each other, with what happened each time and who had to add a sweetener to close it.
Every number on them comes from deals that actually closed, not from a calculator adding two columns. That is the difference between what a player is theoretically worth and what your league will really give up for him.
