I think next year is the big Xavier Willison break-out. He improved drastically in his consistency this year in Cup and brief stints in the NRL. I'd be starting him right out the gate if he has a good pre-season, he's going to be a monster.
If we lose Capewell, this would be my current forward pack -
8. Willison
9. Walters
10. Haas
11. Piakura
12. Riki
13. Carrigan
14. Smoothy/Mozer (Pending pre-season growth from Mozer)
15. Hetherington
16. Jensen
17. Taupau
Depth order: Te Kura, Baker, J.Hunt
Obviously a pretty large problem arises if we lose an edge backrower, Carrigan could cover a hole if the injury happens mid-game, but we'll need to sign at least one more 2nd rower veteran, in case of emergency.
