But he is still falling as is the ball and the ball momentum whilst changed still hits the ground with his hand above it, this isn't rugby grounding the ball is what your trying to not do
. There are plenty of catches that have looked that have been reversed on umpire review, it looks good on first review as most players have present of mind to keep the ball off the ground whilst making a diving catch. Either way it not England's power to keep Duckett out without doing something unprecedented in the game so they can't be accused of bad sportsmanship.
The other is about taking advantage of a situation where the batter isn't trying to do anything to gain one. People have been recalled in the past. And I simply don't care enough about it Bairstow was a fool but Australia should of withdrawn but its done now no point in caring England were unlikely to win even if he was recalled. The only thing that's annoying me is false equivalences like the Starc catch or Bairstow trying to do it earlier in the match when Carey was actually batting outside his crease.
He marked the crease with his foot he doesn't have to do anything with his bat but that's be side the point even if he did ground his bat if he immediately left the crease he'd be out. He was definitely being a dozy pillock. Then again you watch Broads theatrics and you realise how often people don't really check if the ball is dead to the letter of the law. Much like the Mankad I wonder how often this would actually happen in a game if teams regularly looked to take advantage.
