I don't think you know what consistently means. It's happened twice.
Graham broke Burgess cheek in the GF with a head clash. And did very similar the other week.
I'm not saying he should be binned for it but Napa's is no more a precedent or pattern than Graham's given he's done it twice as well.
I just want consistency on head clashes, nothing more. Not one rule for Napa and one for everyone else.
Napa's isn't a head clash. Napa's is a deliberate leading with the head.
