Abstract: A basketball goal system may include a backboard, an elongated support that positions the backboard above a playing surface, a backboard support assembly that connects the backboard to the elongated support, and a goal support assembly with a rim and a support member. Preferably the support member is attached to the backboard support assembly behind a plane that is generally aligned with the front surface of the backboard. In addition, the basketball goal system may include a resistance mechanism to create a breakaway type basketball rim. The resistance mechanism is also preferably positioned behind a plane that is generally aligned with the front surface of the backboard. Advantageously, the basketball goal system may be part of a portable basketball system and/or a basketball system in which the height of the backboard and rim is adjustable relative to the playing surface.
