Wow, a couple of really one-eyed Kiwis on here (a couple, not all!) - what Hore did was despicable - it wasn't anything to do with clearing out at a ruck, it was a swinging arm at the head of a 6'6" second row who had his back turned. Whether Hore has done something like this in the past or not is irrelevant - everyone has a "first time" and it doesn't excuse the act.
It's a shame that, even though he will get a ban, it won't hurt his team like a red card on the day would. It's time the rule in the English Prem is rolled out across the board: ref's can go to the TMO for foul play incidents that they've missed at the time. It would have been a straight red that would likely have changed the game significantly (although I still think that NZ would have won - Wales were dreadful)
Thing is we are used to seeing McCaw be subjected to stuff like this on at times a weekly basis and often nothing happens. McCaw got a forearm to the head recently and the offending player got like 1 week and ended up playing the all blacks in the very next game between the sides a couple weeks later.
If Hore gets more than a couple of weeks then the main difference will be from the player he hit being injured. If that's the case does that mean McCaw needs to stop shrugging off all the foul play he is subjected to stop being so hard and actually get injured so there is a chance the offenders actually may get a meaningful punishment?
I agree if spotted a Red Card would have been a good call and that even though Hore had a very good game a red card would not have changed the result. And yes it was bad, no real excuse for it. I was just trying to figure out what was going through Hore's mind at the time. No it wasn't clearing a ruck but the welsh player was on the wrong side of the ruck and in the way of Hore getting to the breakdown. I think a bit of a push or shoulder out of the way to let him know he's in the wrong spot would have would have been ok but what Hore did was way over the top, and mostly out of Character for him. Up Till now anyway...
