Installed inground basketball hoop?

[Maddog]

Here is a better idea. Buy the kind of post/hoop assembly that bolts to a plate. When you pour the concrete, you set the threaded bolts into the wet concrete at the appropriate locations. After curing, mount the post to these bolts. This allows you to remove the hoop in the future, replace it, etc. Of course, this doesn't work well if you already own the other kind of post.
