A rim mounting plate (26) is mounted to a backboard mounting plate (12) by a resiliently biased release mechanism (16) including an adjustable control (20) and compression spring (18) for varying the breakaway release force and for automatically returning the rim to horizontal after a slam dunk. The rim has a pair of supports (46 and 48) extending downwardly from opposite undersides thereof and joined at a central portion (34) forming the pivot point adjacent the backboard. The backboard mounting plate has a lower portion (52) curled around the central portion of the supports and coined to provide a snug interference fit substantially eliminating vertical and horizontal free play at the pivot point. A protective pinch gap and includes a portion extending vertically downwardly between the backboard and the backboard mounting plate to dampen oil canning against the backboard shroud (58) covers the mounting plates and the gap therebetween when the rim is in its downward pivoted position, to prevent a player from pinching his fingers in the gap.
