I find the
Darren Drysdale story rather fascinating. He stepped over the line and will be punished for it, but in my opinion referees are totally inadequately protected. The more I watch rugby, the more I think "why on earth do we allow footballers, managers and staff to regularly harass refs in football?" Not to mention the internet bullying.
Bare minimum, there should be a rule banning players from speaking to refs except when spoken to, save the captains. Outside that, confronting a ref/complaining is automatically grounds for a yellow.
This is also why a sin bin would be a good idea, to give yellows more teeth.
