How does Joe Launchbury get a 2 match ban for accidentally catching the head of an opponent – causing minimal (if any) damage – while Malakai Fekitoa only gets a one match ban for nearly decapitating an opponent and Sam Cane gets away scot free for laying out Robbie Henshaw with a dangerously high tackle?
I do get why Launchbury was punished. If you aim a kick at the ball in a ruck near an opponent’s head and you get it wrong, your actions are dangerous.
Likewise a swinging arm or a head high tackle is dangerous, no matter the intent.
Either punish all such actions (with consistent punishments), or deem them accidental and unworthy of sanction…
