My favorite saving the ball out of bounds, no-look, luck shot still belongs to JR Rider who hit a 3-pointer while going out of bounds but this over the backboard shot by an Olimpija player ranks up there below Rider's shot and above Popeye "damn he's fat now" Jones luck shot.
I'm sure that gave the opposing team, KK Partizan, some hope as they were already down by 21 in the 4th when the shot was made against them.
