Christian McCaffrey and Jameson Williams have been on opposite sides of 27 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. 1 of them were straight up: Christian McCaffrey for Jameson Williams, nothing else changing hands.
In 3 of these deals exactly one side had to attach something extra, split 0 to 3 between the Christian McCaffrey side and the Jameson Williams side. That is too close, and too small a sample, to call either player the more valuable.
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 Christian McCaffrey prices at 4,381 and Jameson Williams at 2,917, so the market currently rates Christian McCaffrey about 1.5x 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: Christian McCaffrey, plus anything in the third column, was traded for Jameson Williams 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 Christian McCaffrey; positive means that side came out ahead.
Across all 27, the whole-deal value gap runs +24.2% from the side that received Christian McCaffrey, so the side ending up with Christian McCaffrey 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 Christian McCaffrey for Jameson Williams 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 27 deals above are the record of what leagues actually agreed to when these two were on the table together.
