Well, amongst Glamorgan's Welsh-born contingent are numerous good players. Will Bragg, for instance, is a competent keeper-batsman best suited to the longer format. He has a bit of the Shane Watson Syndrome, with only one century from his twenty fifty-plus scores in fist-class cricket, but has recently lost his form and struggled to reach the latter landmark. In comparison to fellow left-handed opener, Gareth Rees, Bragg's stats are quite ordinary. Rees has recently broken into the limited-overs set-up at Glamorgan, and has a total of sixteen first team tons.
The gloveman of choice, Mark Wallace, was born in Abergavenny almost 32 years ago, and has spent the last fourteen of them playing first county cricket. He isn't a top-class batsman, but he is a fighter, and an excellent wicket-keeper. Mike Powell, now of Kent, made his debut two years earlier, and has 27 centuries on his first-class record. He is now past his best, never fully recovering his form from before the life-threatening blood clot that cost him a rib. The rib remains buried at Sophia Gardens.
Swansea-born Gareth Rees would be vital to a Welsh national team.
Dean Cosker, although born in Dorset, can consider himself as Welsh as anyone else in the side. He's a good spinner, not fantastic, but where he is fantastic is at backward-point. Despite being the wrong side of his 35th birthday, he remains as agile in the position as anyone else in county cricket. His rivals for the spinner's spot would be Pembrokeshire's Andrew Salter, a promising offie who relies on flight, and former England Under-19 Nick James, who has been employed by the Welsh county since 2009.
Among the most recent Glamorgan recruits are Chris Cooke, Jim Allenby, Graham Wagg and Michael Hogan, who were born in Johannesburg, Perth, Rugby and Newcastle (NSW) respectively. They will all either qualify by residency in the near future, or immediately by ancestry, and would all add to the strength that Wales could call on. Its not as if Wales would be the only Associate to call on Aussies and South Africans.
Jim Allenby isn't Welsh born, but would be Welsh qualified.
Kenya, for instance, Canada, and Namibia, all of them could feasibly be beaten by such a Welsh side. Not every time, but it would be a pretty fair contest. They'd probably attain One-Day International status, but have to fight to maintain it.
It would also work well to establish a six-nations European competition. Denmark, Ireland, Italy, Netherlands, Scotland and Wales could take turns to host it, But I think Wales could aim bigger, and look to New Zealand for inspiration. Both are countries of a few million people and several million sheep, whose winter sport is rugby and summer sport is cricket, whose cricketing culture is somewhat dominated by their nearest neighbour. Wales, if they backed themselves, could reach such heights, assuming that the cricketing powers that be weren't to block their path.
