Matthew Stafford and Ryan Tannehill have been on opposite sides of 20 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.
None of them were a straight one-for-one. Every time these two crossed, something else was attached to close it.
In 3 of these deals exactly one side had to attach something extra, split 0 to 3 between the Matthew Stafford side and the Ryan Tannehill side. That is too close, and too small a sample, to call either player the more valuable.

Read each row as: Matthew Stafford, plus anything in the third column, was traded for Ryan Tannehill 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 Matthew Stafford; positive means that side came out ahead.
Across all 20, the whole-deal value gap runs -15.8% from the side that received Matthew Stafford, so the side ending up with Ryan Tannehill 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 Matthew Stafford for Ryan Tannehill 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 20 deals above are the record of what leagues actually agreed to when these two were on the table together.
