The NBA Sixth Man of the Year award is given annually to the best player who comes off the bench as a substitute rather than starting in the game. This award recognizes the importance of players who can change the momentum of a game when they enter, providing scoring, defense, or playmaking. The winner is selected by a panel of sportswriters and broadcasters, who vote based on the player's performance during the regular season. The award highlights the value of depth in a team, showcasing how crucial bench players are to a team's overall success in the NBA.
