The reverse between the legs move is great to use against an over aggressive defender that has all of their weight moving one direction and is not on balance. You can plant your same side leg and change directions quickly as you go reverse between the legs to your other hand.
Great ball handlers are able to do moves like this because they have spent the time in the gym mastering the move first. That is why dribbling drills like this are great to use when working on different ball handling moves. They allow the player to get a bunch of repetitions at the same move in a short period of time. This will allow the player to really develop confidence in using a specific move.
