The NABC Defensive Player of the Year is a college basketball award given annually by the National Association of Basketball Coaches (NABC) to recognize the top men's defensive player in NCAA Division I competition.
It has been given since 1987 and was previously known as the Henry Iba Corinthian Award, named after Naismith Hall of Fame coach Henry Iba, who coached at Oklahoma State from 1934 to 1970.
Greg Oden (2007) and Anthony Davis (2012) are the only freshmen to have won the award.
Two winners of this award were born outside the main territory of the United States.
Duncan was born in the United States Virgin Islands, an insular area of the U.S.; by U.S. law, all natives of the USVI are U.S. citizens by birth.
