The problem is this : you could go to any RL game, any team, any ref (includig Thaler) anywhere in the world between now and October and the exact same scenario will be given as a try.
Similarly, if Walmsley moves off the mark tonight will he get pinged like BMM did? No, he'll probably get a penalty for Cas messing around.
Refs and the RFL are trying to make an exact science out of officiating to the point that common sense are dispensed with in favour of obscure laws and unyielding interpretations of the rule.
The rule about players on the floor at the ptb has become a get out of jail free card for players, including our own, to get a dead cert penalty.
Unless a player is deliberately interfering with the ptb or obstructing a player by physically restraining a defender then it should be play on.
