I’d like to see Walker for the potential, but at the same time would prefer we stuck with a defence-orientated centre. Trbo, Schuster, Harper, Saab and Garrick (or if you drop Garrick and throw in Suli) is enough strike. Harper, Schu, Olakautau and Parker are good defenders on the edges. Saab is improving and Garrick is improving (but occasionally pretty suspect).
But as far as potential goes for Walker, I fear his speed is well, well past him and that people are anticipating he is going to return to his 2017 fitness. I don’t even know for sure if he would be any more dangerous with the ball than parker.
The right is Harper’s spot. The left centre is up in the air (suli, parker, walker) and i’d like to see us try transition Tuipulotu into a winger to take Garrick’s spot eventually
