Parker was in a bit of a state too. Kinda 50/50 on Slater not being there, he's dangerous, but both games have been shockers by his standards. Boyd is so massively overrated too, I forgot they had even picked him. I don't think they'll gamble on Barba, Inglis would be my first choice, but I'd be hesitant to move him given the way he's been playing, so Bowen would be the next best.
As for NSW, drop B. Stewart, move Hayne to FB and bring the other Morris in on the wing.
