发明名称 Basketball practice assembly
摘要 A basketball hoop assembly for improving a basketball shooter's accuracy in shooting a basketball. The assembly includes a frame support which is attachable to a backboard. A plurality of different diameter hoops beginning with the largest or "regulation" diameter, and stepping smaller in diameter each have their own bracket for mating with the frame support. The smaller diameter hoops have longer frames so that the horizontal distance between the center of each hoop and the backboard, is equal for all the different hoops of the assembly.
