Or perhaps the citing commissioners actually see all the angles. I not saying that the case, but I suspect they see a lot more than we do, I actually was watching John Kirwan showing how they actually watch etc these things when explaining why Fall (the French 15) shouldn't have been red carded. In that case they went through the whole thing, a bit at a time looking where everyone was coming from, and what they were looking at etc, pausing it time and time again to see where everything is, really was most interesting, and assume they do it in all cases. I actually thought when I saw the Pocock one he actually dragged him down by the shoulder, but I haven't watched it that much anyway so probably wrong. I just thought he would of been YCed for being off feet when he did it, but didn't think he had his arm around neck which is what is required for neck roll.
