I believe he should be suspended for the rest of this year and made to miss the entire world cup as well, as a bare minimum.
Thaiday had stopped moving when he was tackled initially around the legs.
Jeremy Smith came in, had Thaidays entire body open and he went straight for the chicken wing - instant suspension
Cameron Smith came in third, while Thaiday was still not moving, and in a chicken wing hold, and with his torso still open to be tackled, and he inetntionally went straight to the the head/neck area.
I don't care if this tackle doesn't meet the defined criteria of a grapple, it's dangerous, it's an intentional attack on the head and should be graded in the same context as the most sever head high tackles.
he should be getting 6-8 weeks minimum for this, as well being forced to miss the entire world cup.
