I will stick up for Hayne. He's always playing out of position for Parra and that's never good for anyone.
He has pace and power and great footwork - so he'd be a consideration.
If you don't want him - and on current form I can understand that, then Lawrence is a more than capable player to take his place. In form and lightning fast with the ability to switch with his Centre if needs be.
On the other wing - James McManus or Monaghan.
I would prefer to see Monaghan AND McManus together as a centre / wing combo, but NSW will go with Cooper and that makes room for just one of them. They'll most likely go for Monaghan because of experience.
