A jump shot taken while jumping or leaning backwards. It is also known as a "fall-away".
A player performs a fadeaway shot to create space between himself and the defender, making it more difficult for the defender to block the shot.
Former Chicago Bulls shooting guard, Michael Jordan, patented a turnaround fadeaway from the post. After coming back from baseball, he discovered that he wasn't as quick or as explosive as he once was. So, he incorporated a turnaroud fadeaway in his repertoire, making the offense simpler for himself and saving his body from unwarranted punishment.
