I could cop the May no try if it was always ruled that way, which it is not. No way Drinkwater gets anywhere near May but you shouldn't be sending your prop down that channel.
The Api one was one of the worst calls I've seen in the NRL this year. Not only does Mikaele take off, API actually makes a tackling motion, he doesn't slap at the ball, he extends his arms then immediately wraps. He actually tackles Mikaele, the guy hits the ground. How can you be penalised for a slapping action when you bring the opponent down in the same motion?
Agree with Benji on the Skelton one. I can actually cop the Cowboys try where Madden gets barged, if they don't call the Skelton one a penalty. They are both the same category of potential infringement and have to be ruled the same.
I personally think the whole disruptor rule is bulldust, you should be able to ddo whatever you please if you get to the ball early enough and don't physically touch the opponent. Skelton's one he's there first and he doesn't even body-check the opponent, he just wins the ground position. Never takes his eyes off the ball and never looks at the opponent.
