Maybe you don’t agree with every pundit ever, but Grothe is regarded as one of the all time great wingers.
I can’t compare to Irvine or King since I never saw them, but in my era Boustead (early), Wendell, Lote, Offiah, Nagas, B Morris even Folau were standouts. Carne and Hancock were excellent too, but I still wouldn’t put them, ET or Chicka in the class of JAC, who for me is next level dynamic, lightning fast, unbelievably evasive and an unreal finisher.
The one I would have on my other wing is Michael O’Connor - who was sublime even as a part-time winger and had an amazing skill set. Silky smooth, great kicker and a game changer.
Interested as to who you think is “far better”.
