Walker is going real well as an impact player from the bench. His defence is never going to be as good as Harpers, and he wont displace Parker for the same reason. What we have right now is working, and there is no need to make any changes to that formula. Our left and right centre/wing combinations are extremely solid now, particularly in defence. Walker's impact might be enough to take us deep into the semi's, and potentially even further. BUT this needs to happen from the bench. When we can field our best seventeen, our bench should look like this.
14. Walker
15. Lawton
16. Keppie
17. Sipley
(Aloiai for Sipley when available, and Taupau to be played off the bench with Aloiai as starting prop)
