How this trade analyzer works
Every number on this page is projected points added to a starting lineup. We take the median projection across the sources that published one, lay out every starting slot in a league your size, and assign the whole pool to it so nobody is used twice and nobody fills a slot he is not eligible for. A player is worth exactly what the league would lose without him.
Your package is then measured against a reference team, the median starting roster from that assignment. What you see is the gap between the best lineup that team could start with your players and the best without them. So a third running back who beats nobody already starting comes back at zero, and the arithmetic says so.
Adam, who runs MustDraft: “I'm in three or four leagues every season, and the one with my friends has been running for more years than I'd like to admit. Every trade I've regretted was one I made from my gut on a phone at work, which is why this shows both sides in numbers before you hit send.”

What the range means
The sources disagree, so we re-run the comparison twice more: once with one side's players at the low end of what the sources say and the other side's at the high end, then the other way round. If one side is still ahead in both, we name it. If the range crosses zero, the sources genuinely don't separate the two packages and we say so instead of picking a winner. The range is disagreement between sources — it is not a probability that the trade works out. The practical rule: when the range crosses zero, the value argument is a coin flip — decide on roster fit and bench depth, not on the number.
What this can't tell you
It knows nothing about your actual roster, your record, your schedule or your bench. It is an estimate against a reference team, not a prediction that anyone will accept the trade. Consolidating two starters into one costs you a roster spot, which the arithmetic accounts for but your bench depth doesn't — that part is still your call.
Reading the verdict like a manager
Treat small margins as ties. A package that wins by a point or two of lineup value is inside the normal disagreement between projection sources, and torpedoing a fair offer over a rounding error is how leagues stop trading altogether. The verdict earns your attention when the gap is large and the range stays on one side of zero; that combination means every reasonable projection agrees about the direction, and only the size of the win is in dispute.
Two-for-one trades deserve one extra thought. Consolidating two useful players into one better player usually wins the arithmetic here, because the second useful player was upgrading a bench slot, not a starting one. Whether it wins in your league depends on how badly you need that roster spot back: shallow benches and heavy bye weeks make depth worth more than any reference team can see.
Your settings change the answer
Scoring format and roster rules move real value, so set them before you judge anything. Full PPR pushes pass-catching backs and possession receivers up the board relative to standard scoring. Superflex leagues start a second quarterback, which roughly doubles how many are startable league-wide and lifts the whole position; a quarterback trade that looks lopsided in a one-quarterback league can be dead even in superflex. The same two packages can produce different verdicts under different settings, and both verdicts are correct for their league.
Redraft values are not dynasty values
Everything on this page prices the current season. A 30-year-old running back and a 22-year-old one with identical projections are worth the same here, because this year they are. If your league keeps rosters year over year, price the same trade on our dynasty board as well, where values come from what real dynasty managers actually traded, and let the two answers argue it out. A weekly start-or-sit question is a different tool again: the comparator is built for that.
