True -
The dynamics of each collision and how players arrive at each can be different. One example I can think of is going back to our debate the other day on the wales match thread re speed/ force.
The amount of force that Ellis Bevan could have generated in his 2 step run up into a stationary Nick White I imagine would be less than what Kerevi and Morgan collectively generated running at each other from 20+ metres. Nick white is much lower to the ground vs Morgan carrying into contact - all different variables.
I think they got the Bevan decision wrong, but its a 'different' hit and we should have seen two red cards but for different contexts
That's not thw way I remember the incident JR2. Nic was crouched waitng for the ball to come out of the ruck. the Welsh No 9 (assume it was Morgan) came around offside and took Nic out without the ball, and in the process hit him head on head. Should have been :
i) penalised for offside,
ii) penalised for taking out a player without the ball,
iii) penalised for taking out the halfback in the vicinity of the ruck; and
iv) carded for head on head contact foul play.
EDIT: And what of Wainwright(?) lying across the back of the ruck interfering with Nic's ability to get into position?
