Cannot find NFHS rule

I've wondered for years about this. What is the deal with OOB/rectangle v. not OOB/fan? This apparent inconsistency has existed for years, so there must be a reason for it. Right? Anybody care to enlighten me?

For that matter, why have fan-shaped backboards at all?

First, why fans? They are far cheaper, and last forever. If you are in an area with lots of fan backboards, they probably don't have the money in the school system to afford the plexiglass.

As for the difference in the rule, I think it is simply that there is no dividing point for the top of the backboard on a fan backboard. But maybe one of the geezers has more to offer.
