The 2006 NBA Slam Dunk Competition between Nate Robinson and Andre Iguodala drew much criticism because players were not penalized for missing a dunk attempt. Consequently, Robinson attempted a single dunk 14 times before completing it. Prior to the 2007 competition, the NBA changed a few rules to prevent excessive dunk attempts. Each participant has two minutes to complete their dunk. At the end of the two minutes allotted, they then have their number of dunk attempts limited to two.
