Goatending?

[vbzebra]

Ok, may be a stupid question, but here goes

kid driving for layup, ball hits off backboard (layup style) still going up is NOT above the rim and is NOT in the imaginary cylinder, defender does his best LeBron "get-that-weak-mess-out-of-here" block of the ball after it hits the backboard (but again, with above parameters mentioned). NBA has it as goaltending. That we know..

My question is, is this goaltending in NFHS? I can't find anything in the books that says it is. The books only have to do with swatting the ball when it's on its DOWNWARD flight, or is IN the imaginary cylinder that has the ring as its lower base.

so WHY is this called goaltending in NFHS? Not trying to be a smartie, just honestly asking. And please, if you find something in the books to back up the fact that it WOULD be goaltending, please reference. Thanks
