Who's Guarding FAQ
Is Who's Guarding a forecast?
No. It is history, labelled with its sample. A projected starting five is not a defensive assignment, and the numbers do not show that a defender moved shots or passes to anyone.
How is the matchup measured?
Field goal percentage is his summed makes over summed attempts against the defender. How often he shoots is 10 times his attempts over tracked partial possessions, compared with every other defender in the same games, and only in games where his tracked attempts add up to his box score.
How are teammates compared?
His games are split at the middle of the defender's guarded time on him. A teammate's rate is 36 times his summed stat over his summed minutes in each group, and each side needs 3 games. With too few meetings, plain averages from the meetings are shown instead.
Which games count?
Final regular season games from 1 January 2024. Teams are the teams each player played for that night, so traded players stay in the history.
