Largely the team in the first post, but I don't actually remember Barry Williams playing so haven't included him (I was aware of him, but don't recall him... doing anything.) and had to choose Hibbard because Huw Bennett was really the only other option. Byrne and Parker are in for their form from years gone by rather than right now. Parker would just about make the Ospreys second XV nowadays, let alone an all-time side. I've got a feeling there's another player who could have come in at centre, but I just can't picture who. Possibly Tommy.
15. Lee Byrne
14. Tommy Bowe
13. Sonny Parker
12. Gavin Henson
11. Shane Williams
10. James Hook
9. Justin Marshall
1. Duncan Jones
2. Richard Hibbard
3. Adam Jones
4. Ian Gough
5. Alun-Wyn Jones
6. Jerry Collins/An in-form Ryan Jones
7. Marty Holah
8. Filo Tiatia
Just read the post a few above... Gibbs, Bateman, et al would probably all replace Parker.
