george north springs to mind (and im not even welsh)
Hmmm Conrad Smith or Ben Smith. Or really just any smith haha
The best one on one defender beater of all time was Jason Robinson without doubt. Recently, Shane Williams had been amazing on that situations.
Richie McCaw in the loose. Carl Haymann in the scrum. Deon Muir taking the ball off the back of the scrum. But I suppose you really mean a back with ball in hand? OK: Gareth Edwards and Serge Blanco. For recent payers, Shane Williams.
