From watching the replay of the Barber sin binning I'd say its for back chat just from the ref's and Barber actions after the whistle goes. As far as I know the warning signal is still a thing so Im not sure it were for repeatable offences. Im not sure the ref's decisions had too much bearing on the result and Im sure theres multiple things evening it up, like the forward pass in the tackle before Fev's first try, its a good couple of yards forwards but on the flip side how many penalties did we get near our own line in the first half that let us off the hook?
With just a little bit of the rub of the green in other areas and we probably win the game it were that close. Jouffrett does not pull up and we probably win the game, Murray gets another yard we win the game, the Fev try off that kick where the bounce was horendous for Jouffret, that does not happen we probably win the game. Its really fine margins and exactly what we want to be seeing away from home against the best team in the division. Not a lot of room for error from now on but if we can take the two points from the Leigh game we will still be in a pretty decent position already playing those two teams once.
