The 2012 NBA Slam Dunk Contest will have a completely new field when it takes place as the culmination of All-Star Saturday Night from Amway Arena in Orlando. Defending champion Blake Griffin and top challenger JaVale McGee are out, with a new field of four being led by Paul George of the Indiana Pacers.

George will be joined by three other young high-flyers -- Derrick Williams of the Minnesota Timberwolves, Chase Budinger of the Houston Rockets and Jeremy Evans of the Utah Jazz. Evans replaced Iman Shumpert of the New York Knicks, who suffered a late injury.
