9.2 Throw in provisions

[jritchie]

Just a quick question. Some veteran officials and myself were talking about a throw in from under the basket that hits underneath the backboard. From the case book and rule book it says it's legal to hit the sides and the front face coming from out of bounds because they are inbounds, but neither says nothing about underneath the backboard, which is also inbounds. So I am saying it's legal to come from OOB on a throw in and hit the bottom of the backboard and come into play legally! I have been told by some that it's illegal and they have called several violations in front of me. AM I MISSING SOMETHING???
