Alvin Kamara and Javonte 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. 2 of them were straight up: Alvin Kamara for Javonte Williams, nothing else changing hands.
This is the part a calculator cannot tell you. In 10 of these deals exactly one side had to attach something extra, and 6 of those 10 times it was the Alvin Kamara side (4 the other way). The side that keeps having to add is the side holding the lesser asset, so the market has been treating Javonte Williams 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 Alvin Kamara prices at 44 and Javonte Williams at 2,036, so the market currently rates Javonte Williams about 46.3x 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: Alvin Kamara, plus anything in the third column, was traded for Javonte 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 Alvin Kamara; positive means that side came out ahead.
Across all 27, the whole-deal value gap runs -22.7% from the side that received Alvin Kamara, so the side ending up with Javonte Williams 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 Alvin Kamara for Javonte 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.
