This is the letter of the law re releasing immediately, but if you're going to allow some effort to clear out a man on the ball, you must also allow some time to place the ball, Rugby would be hella entertaining if it was always released immediately, the pace of the game would be insane. But it isnt the way the game has been reffed for years now, so no, I'm sorry but Barnes made a perfectly logical decision in this case
If you watch a full rugby game with an eye on this, you'll see its not uncommon for the ball to be released on the attacking side several seconds after hitting the ground
At the very least, you've got to admit it's not a shocker, and is a logical conclusion to come to when seeing the play? Barnes didnt miss it, he just saw the opposite as you, and instead what I see
