GT for the win

[Nevadaref]

Have watched it three times and still am not certain that his action is illegal.
I see the right hand in the net, through the ring, which then withdraws prior to the arrival of the ball on after the bounce. This is followed by his left hand swatting the ball away after it contacts the ring for the 2nd time. I can't tell if the ball was still within the cylinder or not.

Not sure about NBA terminology, but for NCAA/NFHS the decision would fall under the BI rule, not GT, because the bouncing ball was on the way up, not down, when touched.
