I did not drop him, but I wobbled my defender backward deep into the paint last week. It was one of those situations where I'd been fortunate enough throughout the game to penetrate ad nauseum. So when the time came where I thought my defender would be sitting on the dribble drive, I was able to execute an in-and-out to step back, leaving him backpedaling, crab walking and fighting himself to stay upright. Contrary to other nearly ankle breaking moves I've executed in the past, I was able to knock down the subsequent triple in this case.
Here is Tim Hardaway's dramatization of my move: http://www.youtube.com/watch?v=y_kX6mQh8Yc#t=2m39s
