At the high school, college and professional levels, trophies are awarded to championship-winning teams, as well as the player deemed most valuable to his team in a given season. Trophies are sometimes given for other reasons, such as performance in a championship game or off-the-court contributions to society.
For example, in the NBA, the Larry O'Brien Trophy, representing a basketball resting on the rim of a hoop, is awarded to the team that wins the championship series. The National Association of Basketball Coaches Trophy, a crystal basketball, is given to the winner of the NCAA Division I basketball tournament.
The Naismith Trophy is awarded to the top player in college and high school basketball, as determined by the Atlanta Tipoff Club. The Maurice Podoloff Trophy is awarded to the NBA's most valuable player, as determined by U.S. and Canadian sportswriters and broadcasters.
Sometimes trophies are awarded for accomplishments that don't require a player to have an excellent performance on the court through an entire season, especially in the NBA. During the NBA Finals, the Bill Russell Trophy is awarded to the best performing player of that particular series. The J. Walter Kennedy Trophy is awarded to an NBA player who has displayed outstanding service to his community off the court.
