Is sevens "real" rugby?
I worry a bit about sevens. I prefer 15-a-side rugby. And I wonder whether rugby should be in the Olympics.
In 1883 two Scottish butchers, Ned Haig and David Sanderson, stumbled on an idea to make money for their club, Melrose. They invited other teams to play a shortened version of the game with only seven players in each side. From 2016 it will be an Olympic sport.
As inventors they joined a list of Scots who gave us things like the TV, car tyres, antiseptics, golf, the decimal point, logarithms, marmalade, the tarmac road, raincoats, penicillin, the telephone, whisky, economics, and, of course, the US and Chilean fleets.
Only the Chilean navy got stuck in its particular part of the world, as the others have spread right across the planet.

And in case you think I am being anti-my neighbours, let me acknowledge that the rest of the UK did indeed invent almost everything else in the world whether sporting or not.
What Ned and David probably never realised is that they had invented rugby's biggest selling tool.
It would be nice in Scotland to see more of those 2,500-strong crowds who turned up to watch Currie play Ayr at the weekend in the 15s game rather than have this time of year dominated by sevens in Scotland, but I have to accept that sevens is taking over the world and the Melrose tournament is superb.
And do you know what makes it rugby's best selling tour? It's now an Olympic sport. A wee game, tweaked from its English source, will now have money invested in it like never before.
The Chinese, whose army has been coached by former Scotland coach Frank Hadden, will now invest heavily in rugby, as will the US and very probably every major economy in the world. There are rumours that the Chinese army wanted volunteers to try a new game called rugby, and 10,000 signed on the dotted line.
In small island economies like Fiji it is the principal game, and as a marketing tool it has few parallels.
The seven-a-side version of rugby will now be seen across the world when played at the Olympics from 2016 and the profile of rugby will never be the same again as kids will see the sport and want to play it for the first time.
Now, this is superb for the sport, but is sevens "real" rugby? I suppose it is, but what I regret about sevens is that, in general, most of the blokes who should be running around in the sun and getting faster and fitter - namely the front row and the second rows - don't have a role.
The end of this season will be a beautiful contrast between the Heineken Cup, the Super 14, the Guinness Premiership, the Magners League and the IRB Sevens.
And then we have sevens at the Commonwealth Games in Delhi later in the year. Rugby joins tennis and golf in the Olympics is just six years.
And I wonder if that will be all good for the sport? Or even if rugby should be in the Olympics?
