I can't see Des blooding a young half.......he has been resistant to trying young guys his whole coaching career and I don't see that changing this weekend, especially for a key spot like 5/8.
He'll stick with what he knows and just slot in guys to the vacant spots. Does anyone know if Cuthbo and Suniula are fit ?? If Suniula is out, than odds on it'll be Hello to centre and Farrar to wing. Rodney can slot in for Glenn at Lock, Hall and JWH/Cuthbo to start in backrow. Bench = Rose, LeSnak, Cuthbo/Mauro/Morewood/JWH.
If Suniula is fit then the only other option I can see is him on one wing, Farrar on the other, Hello to centre and Iro Williams onto bench and into backrow rotation.
Anyway it's going to be a tough ask.
