Broadacres:
For any of the recent sin-binnings have any of the fouled players had to go for HIA? It's almost like players are coached to ensure play stops and anything marginal is going to be given once reviewed by the VR.
Listening to the refs explanation, anything along the lines of "it's direct contact to the head with force...." - as for the two on Thursday - then it's certainly surprising they aren't sent for HIA, given all of this was brought about under the guise of player welfare.
At some point the RFL will cotton on, HIA's will happen, players will fail them and the practice of staying down will fizzle out for a while, then gradually creep back in and round and round we go.
