Maloney was pretty clearly held up I thought.
His earlier one was closer to 50/50, but we got the rub of the green on that one.
Mason playing on was fine. He wasn't held and got up, then was tackled but his arm didn't hit the ground. He's free to offload in that situation.
Not sure what all the fuss with Sione supposedly taking the ball dead is about. I would have thought it logical that if he steps out first and then touches the ball the ball is dead, in much the same way that if he was an attacking player trying to score a try, when he batted the ball back he would have to have come from inside the field of play. Happy to be proven wrong on that one though if someone actually knows the rule on that.
