Because most players know it constitutes a penalty. I could've put in that hit.

Whether he's a foot off the ground or a mile off the ground is irrelivent surley?

He pretty much hit him spot on as his feet were landing back on the ground. A penalty would never be given for that kind of tackle as there are inches (if anything) in it.

I'm also not 100% sure about the rules or ref's guidelines on this one. If it is at the other end, and you are going for a try, what is to stop you leaping off the ground to get over the line so the defence can't touch you? I'm not sure if this only applies when you are defusing a high kick, which Hall wasn't doing in this instance.

Good hit but I am more impressed by Hall getting the ball under pressure on his own try line and keeping hold of it.

The rules stateIt is illegal to tackle an opposing player attempting to field a kick whilst the player is in mid-air. The catcher must have returned to the ground before being tackled.'"
