I don't think there's any realistic prospect that Scotland are going to vote for independence. The opinion polls suggest they won't, and I speak to Scots on a daily basis (admittedly from the more conservative leaning golf community) and am yet to encounter anyone who wants independence (or admits it). Come to think of it, the greater advocacy I've heard for Scottish independence tends to come from South East England!
Rory has a bit of an issue though, as I understand it as he's qualified for either team. If he plays for GB one community will turn on him, if he plays for Ireland, the other will
Last I knew he was veering towards the pragmatic decision and not taking part in a tournament which is hardly that important to him, and which could have ramifications beyond if he's seen endorse one country/ religion/ or political philosophy over the other.
I would imagine Poulter would fancy sunning himself in Rio though and he'd be an obvious candidate.
Personally I'm of the view that Olympics should be the pinnacle of achievement in the respective sport that it plays, as it is for track and field and a few other events. If the sport concerned has a higher accolade available to it, then I'm far from convinced the Olympics should host it as a professional sport. So I would include golf, tennis, and football in the list of sports that shouldn't be rostered.
