Neither did Folau.
Apparently, who knew!, the messages a player sends, verbal, non-verbal and written, matter. Not that i like it. Personally, i agree with you in the fact that no word other than a direct and undeniable threat to do physical harm should NOT be at the same level as actual physical harm. But that's me. Just for clarity, i dont believe for a sec Savea wanted to kill him. Cant believe i have to explicitly clarify. These times...
But hey, I mean, it'd be 'a bit' hypocritical for someone, anyone, to have asked for Israel Folau's head for what he did on instagram and turn a blind eye with Savea for what he did, mid game, live, in front of the ref.
I know, one is ARU's thingie and the other a WR/SR thing, different animals. Tecnicalities aside (they are important, granted) the fans'/pundits' outrage or lack thereoff should still aim at avoiding double standards. as a principle at least.
