I think he's a C-Grade winger and a Z-grade full-back, personally.
I've never really seen him have much impact off the bench, either, unless i'm misremembering?
I realise this is a boring comment to make - but genuinely would prefer a young kiwi in there if we're just going to use him as an impact sub usually or as a winger; even someone like Rogerson who hasn't set the world alight.
