Different backboard materials will vary greatly in how well the basketball bounces or "rebounds" off of the surface. In increasing order of reboundability, backboard materials would rank as follows: plastic, polycarbonate, acrylic, and then glass. While this difference in rebound may seem trivial to many basketball players, backboard material on basketball hoops can help or hinder a player's shot development. In particular, a shot that is used often as a player advances his or her skills is the "bank shot." This shot describes the player shooting at the backboard with the hope of bouncing the ball into the rim. With lower-end materials - like plastic, polycarbonate, and acrylic - the bank shot can become greatly altered if the backboard absorbs the impact of the ball.
