How does the draft simulator work?
The draft simulator runs a mock draft against realistic opponents and grades your picks on ADP value per round: whether you got a player at, above, or below where the field was drafting them, not a guess at how your season turns out.
What the grade means
Each round's grade compares the pick you made against average draft position at that spot in the draft. A pick graded well got a player later than the field usually does; a pick graded poorly reached for a player ahead of where the field values them.
That is a value grade, not a season prediction. It tells you whether the pick was efficient relative to the room, not whether the player will score more or fewer points than expected.
Running a mock
Pick a draft slot and league size and the simulator drafts the rest of the room around you. No account is required to run a mock draft.
