For me the situation, re: is the ball out or in. At the scrum it looked to be out initially but then it was picked up by a Sader, taken to ground, then a ruck quickly formed. Hooper went for the ball a fraction too late (ruck had just been formed) which would explain the referee's change of mind, the situation simply changed very quickly. It would also explain Hooper not getting penalised for being offside because it all happened so quick & he did retreat back behind the offside line. Personally, I see nothing wrong here but that's based on memory of what was a pretty quick event, would like to see a replay. I don't think Jackson is doing a bad job regarding the ball in or out rulings specifically.
Saders missed tackled mentioned. Have missed a few but they have been mainly defending in this game. I thought the defence looked good for the most part.
