Here are 27 dunks that have NEVER been done in the NBA Dunk Contest! There are actually 31 variations of dunks in the video but since some of them were somewhat similar to another we counted them as one. 2 more (at least) dunks that aren’t included in this video which are windmill dunk from the freethrow line and between the legs from the freethrow line. However if the NBA invites James White to the dunk contest we can expect to see those 2 almost guaranteed.- Ballislifedotcom
