If FdK passes it somewhere else, we don't penalise blue because it was immateriailwell, I cant say cos im not in his head. Though I woluld say he was a pillock noty to have laid prone (or even supine!) to minimise his risk etc.
As it is, as he he didnt get PKd for it whatever he did he "got away with it". Only BNOK can explain why. Presumably the TMO/whatever didnt call in it in either 9eif that is in their remit but who knows frankly as they seem to make it up etc etc)
If FdK passes it at blue we don't penalise blue because FdK threw it at him
So blue is offside, in the way,and immune from sanction
