This Shooting Trainer, designed by University of Michigan Head Coach John Beilein, is made from the same Composite Leather as a THE ROCKŪ Game Ball! The "BEILEIN" Black Line helps the shooter analyze and correct ball rotation to improve accuracy and control from any distance.

"We started out with a Magic Marker, now we have a custom game quality instructional Basketball by THE ROCKŪ!

Every one of our players shoots with the ball hundreds of times a week. It certainly works for us. Proper rotation on the ball is essential to being a good shooter. This ball teaches it daily.

I will never coach again without using the "Beilein Ball" as a shooting aid.

No doubt that this Ball has improved our overall three point shooting." - John Beilein - University of Michigan
