Kidd, 40, was listed first on 91 of the 355 ballots returned by NBA players. Other finalists, one from each division for the honor, were Chicago's Luol Deng, Golden State's Stephen Curry, Memphis' Mike Conley, Oklahoma City's Nick Collison and Orlando's Jameer Nelson.
Kidd also won the award last year when he was with the Dallas Mavericks. He is the second player to be voted the Sportsmanship Award more than once. Grant Hill won three times (2005, '08, '10). Deng took the honor in 2007 and Curry won the award in 2011.
The award is given to a player who reflects the ideals of sportsmanship -- ethical behavior, fair play and integrity -- in amateur and professional basketball. The trophy is named for Joe Dumars, the former Detroit Pistons guard who won the first Sportsmanship Award in 1996.
