The ball is thrown to the coach and the player runs fast against the cone.
The cone is touched by the hand and then fast return.
At the moment the cone is touched, the backcourt player runs forward and the coach lets the ball roll slowly forward.
The player, who touched the cone runs against the rolling ball, pick it up with one hand and passes it immediately from the floor to the running backcourt player, who shoots.

Adjust the distance in such a way that there is no time to stand up and throw the ball in a normal way.
The drill is made to train the ability to pick up a lost ball quickly and pass it to a fast runner.
