well, about it now we're at the crease. :P I remember Scott Styris' antics were similar in the 2003 WC. Instead, the runs he took off that delivery were deducted. On the contrary, it's pointless whether or not a throw obstructs the batsman while he's behind his crease, unless he makes a late run. Because there's no other basis to appeal. If Stokes was behind his crease, Starc simply wouldn't have thrown the ball in the first place (unless he meant to be vicious/aggressive) and none of it would have caused a moot point.
Throw obstructs the batsman? I think you mean to say that its pointless whether the batsman obstructs the field or the throw if he is already behind the crease. Assuming this is what you are saying.
Again I think even if the batsman is sitting in his crease he cannot just keep swating away throws. He has to be out if he un-necessarily interferes with the play.
