In my opinion much of the angst about throws is because of the definition being so loose. Hold the ball and touch it with your fist is very easy to do incredibly quickly and very hard to dispute as a throw.
Yes, and as I have posted long ago, and as MDJ repeats above, "The only explanation for why it is let go is the AFL wants to keep the ball moving so don't mind it getting out of stoppages in almost any fashion." So many HBs are in fact quick scoop throws; the players are excellent discerning when they are on the wrong side of umpires (Libba is a master) but it's only penalised for the really blatant ones where no 2nd hand is in touch with the ball.
The ball buried in packs is a bad look for the game (any sport), the ball out and moving is what the AFL want for their sponsors and TV coverage, along with high scoring to arrest the perceived drop in over recent seasons, especially prior to Shocking's supposed great 'reforms'!
It's the same with guys getting tackled almost immediately after taking possession (like Baker on Sat.) held down in tackles, pile-on by other players, cannot possibly release the ball and had a mere split-second of prior ... HTB. But most times, except for certain RFC players, Dusty being another example, it's a ball-up.
People keep failing to understand, Gil's regime has been all about the game's revenues, not it's integrity - whatsoever.
