The night before, in the ashes test, Walsh arrives late into a kick contest leaps wildly and gets the england player (Herbie?) shoulder to head. Not nearly the same impact as Katoa, but he got him.
After much time wasting with the TMO, Atkins eventually bins him, didn't really matter to the game, England wouldn't have scored against 9 players the way they were going.
Anyway - the whole time the pommy commentators would not shut up about how terrible this decision is, how's its ruining the game, how they need to play on and get over it, didn't even hurt him etc, etc.
14 hours later a player nearly dies. These two things are absolutely related, got zero tolerance for the games gone soft crowd after this, its so bad and any coach, ref, official, doctor, player who minimises head contact, should get hauled over the coals going forward, and they should tinker with the rules to reward ye olde legs tackle and make the players practice it (yes, lots of player including our own
Wayde Egan end up with more knocks from putting their head in the wrong place, but it's mostly bad technique after 20 years of upright gang tackling).
People will get used to it, we got used to no more SBW style KO shoulder charges, which have also killed people.
Everyone shits on union being red card happy but at least they have some deterrents.
Its just entertainment.
