Brock Purdy and Dak Prescott have been on opposite sides of 29 real dynasty trades.
Not simulations and not a calculator lining up two numbers. Every one of them is a completed trade from a public Sleeper league, graded at the player values that were current on the day it happened.
Most of those were larger deals with other pieces attached. 2 of them were straight up: Brock Purdy for Dak Prescott, nothing else changing hands.
This is the part a calculator cannot tell you. In 7 of these deals exactly one side had to attach something extra, and 5 of those 7 times it was the Dak Prescott side (2 the other way). The side that keeps having to add is the side holding the lesser asset, so the market has been treating Brock Purdy as the more valuable of the two.
Everything above is priced on the day each deal happened, which is the only honest way to grade a completed trade. It is not what they cost now. Today Brock Purdy prices at 2,114 and Dak Prescott at 1,462, so the market currently rates Brock Purdy about 1.4x the other. A pair can lean one way across its history and price the opposite way now; that gap is the whole reason to check the deal in front of you rather than the deal someone made in 2023.

Read each row as: Brock Purdy, plus anything in the third column, was traded for Dak Prescott plus anything in the fourth. An em dash means that side sent nobody else. Margin is the value gap at that day’s prices from the side that received Brock Purdy; positive means that side came out ahead.
Across all 29, the whole-deal value gap runs -4.7% from the side that received Brock Purdy, so the side ending up with Dak Prescott has generally come out ahead on face value. That measures the entire trade, every piece included, not these two players against each other.
A calculator answers “is Brock Purdy for Dak Prescott fair” by subtracting one number from another, and it gives every manager in your league the same answer. That tells you nothing about whether the trade closes. What closes it is whether one side has to attach a piece, and which side that usually is. The 29 deals above are the record of what leagues actually agreed to when these two were on the table together.
