Inbounding and backboard slapping

[JS 20]

I had this same situation earlier in the year and posted my question on this forum. B1 hits a shot, A1 catches directly under the net after it goes through, makes NO attempt to get OB, throws an outlet pass to A2 who goes up court. I hit the whistle and signal a throw-in violation. I don't feel 9.2.2 C covers my situation or yours b/c the player doesn't make an attempt to get OB, however I still say this is a violation. If you disagree with me, what if before you can blow it dead, the defense fouls? Then there's a problem. So I say you have a violation for not having a legal throw in.
