His back issues don't worry me, his injuries since do. Which are different and again, just simply unlucky.I do get that and not trying to be harsh (also noting that again, these are large generalisations given you can't classify performance and potential into only 3 tiers) - however, Gunston has now played only 12 of the last 37 matches, his back issues worry me, and he will be 31 come the start of next year.
Put that all together and I think there's enough there to say there's a bit of risk there, and I would put it 'in the realms' of Wingard (again - not saying it's equal, but don't think they are worlds apart).
Not sure about his goal kicking, no doubt he'd be working hard on getting back to where he was (as an elite setshot) because kicking in general play around goals he's still very good and he's still a very good field kick.
