The NBA Slam Dunk contest is one of the oldest and most anticipated events during All-Star weekend. While some of the NBA's most talented dunkers will take center stage once again, the 2013 NBA dunk contest will have a new twist.

This year, the six competitors will be grouped by their conference affiliation. Indiana's Gerald Green, Toronto's Terrence Ross and New York's James White will represent the Eastern Conference. Utah's Jeremy Evans, Denver's Kenneth Faried and Eric Bledsoe of the Clippers will represent the Western Conference. Evans is the defending champion, but will face a loaded field, including Green, who won the 2007 dunk contest.

The 2013 competition will be broken down into two rounds. All six players will attempt two dunks during the first round with their efforts being scored by a group of judges. The player with the highest combined score from each conference will advance to the final. There, both players will again attempt two dunks. The winner will be decided by fan voting.

Assuming every contestant completes both of his dunks in both rounds, Saturday's dunk contest will include 16 dunks. Evans and Green are previous dunk contest winners, but White is the betting favorite, according to Bovada.
