Disagree FFV. Wright's head would've be pushed forward along with his body if he had been hit in the back of the head as well as the body. However in the photo his head recoils backwards as the collision with his upper torso pushes his body forward. In other words whiplash and if severe enough possibly the cause of his concussion. I don't know why our QC said Wright's head hit the ground as it didn't look like that happened either
.
Looking at that photo, it seems
possible that Cotchin's shoulder made contact with the side of Wright's head. I think that is undeniable that is looks
possible.
Looking at the incident in slow-mo, it doesn't really look like it, but it is possible.
Seems more likely that the whiplash caused the concussion, but as I've said numerous times, once you decide to bump when you clearly have other options, you become responsible for the damage caused, whether or not the damage was "accidental" or not caused by the initial impact. You don't have to like the rule, but that's how it is.
I actually support the rule as it is now written. People whinge about the game becoming netball etc, but in the old days, shepherding and blocking were never intended to be taken as opportunities to knock your opponent into next week. They were opportunities to impede your opponent and give your own player time and space to dispose more effectively. The force with which some blocks and shepherds are dished out these days is excessive and unnecessary in many cases the intention has become to maim rather than impede.
