Backward Crossover Video mini lesson by Instructor Team Leader Alan Noble.
The crossovers shown are best used for gaining acceleration and lateral mobility and should not be done in a one on one situation.
Also players shouldn't do the "reach in" technique until they have already mastered normal backward crossovers powerfully and to full extension. When players try to do the reach in and have not fully grasped the technique of the normal crossovers, it tends to make the crossovers worse rather than better. It would be like adding in a puck to the forward stride before the player has the normal stride down, its just too much to think about right off the bat and should be built up to in a progression.
