I reckon most would go with 12 SBWs and a Cam Smith.And I am not sure that "league prop" means anything in league anymore either. Now there's middle forwards, edge forwards, and so on. If they could have 5 SBWs with a Cam Smith in a forward pack, every team would.
Ok, so hypothetical:
The Reds have signed him, done whatever they need to get him ready for Super Rugby season 2015 - how do you use Fifita?
I was thinking like a Will Skelton style- run him on with 25 to go to bash people for a while.
Or, alternatively, Play him at 7 for the first 30 then run Gilly on for the rest so he's playing tired and battered opposition.
Or he could just play as an 8?
