Yeah - the 4x4 was "necessary". This is basically one of those glorified, overgrown Nerf hoop so it has one of those "door hangers" on the back to hang it from. I basically mounted the 4x4 to the cinder block and cut a slot down the center of the 4x4 lengthwise so the hoop could be taken up/down as wanted. I then had to actually put another 4x4 at the bottom of the backboard to support it so when the ball it it, it didn't just bend backwards and rattle around. It was horrible overkill for such a silly thing, but I did it with my son so he learned something. He and his friends have been loving it. It's an eyesore, but so be it.
