<P> Michael Jordan popularized a dunk referred to by some fans as the "Leaner". This dunk was so called because Jordan's body was not perpendicular to the ground while performing the dunk . TNT viewers rated it "the best dunk of all time" over Vince Carter's between - the - legs slam . </P> <P> In the 2000 NBA Slam Dunk Contest Carter used an elbow hang along with his reverse 360 windmill dunk and between - the - legs dunk . When performed, much of the audience was speechless, including the judges, because none had seen these types of dunks before (Carter's first round 360 windmill dunk is reminiscent of Kenny Walker's 360 windmill dunk in 1989 except that Carter spins clockwise, where as Walker spins counter-clockwise). </P> <P> In the 2008 Sprite Rising Star's Slam Dunk Contest Dwight Howard performed the "Superman" dunk . He donned a Superman outfit as Orlando Magic guard Jameer Nelson tied a cape around his shoulders . Nelson alley - ooped the basketball as Howard jumped from within the key side of the free throw circle line, caught the ball, and threw it through the rim . This dunk is somewhat controversial, as his hand was not over as well as on a vertical plane to the rim . Some insist that it should in fact be considered a dunk because the ball was thrust downward into the basket, meeting the basic definition of the dunk . </P> <P> During the 2009 NBA dunk contest, Howard had a separate goal brought onto the court, and the rim was noticeably significantly higher than a standard goal . Howard, after going into a 1950s - era telephone booth and again fashioning the Superman attire, caught a pass from Nelson and easily completed a two - handed dunk on the higher goal . While this was not performed for record - setting purposes, the dunk received a perfect score and a warm response from the crowd, in part because of its theatrics . Also in this contest, 5'9" guard Nate Robinson wore a green New York Knicks jersey and green sneakers to represent Kryptonite, playing on Howard's Superman theme . He used a green "Kryptonite" ball, and jumped over the 6'11" Howard prior to dunking . This dunk and the theatrics could have won the competition for Robinson, who was voted the winner by the NBA fans . Robinson then thanked Howard for graciously allowing him to dunk over him, asking the crowd to also give Howard a round of applause . </P>
