1 on 1 basketball competition drills are great because they allow you to practice your offensive basketball moves that you have been working on against a live defender, and also work on defense. The 1 on 1 spot triple threat basketball drill is going to allow the players to play 1 on 1 from anywhere on the floor (3 point line area and in). It will help them to practice scoring out of the triple threat, and being strong with the ball.
This drill will also allow you to work on your defense as well, because you are in a situation where there is no help defense and it is just one on one. As a defender you want to work on guarding without fouling, and as an offensive player you want to learn how to read the defender and use the right move to get a good shot off. This is one of the better defensive basketball drills for teaching a player to be able to guard without any help defense.
