I personally was a bit underwhelmed with him when he first burst onto the scene- scored a heap of tries (as wingers in good sides tend to) but didn't really stand out in terms of the speed, evasiveness etc you would expect from an elite winger. Just seemed like a good, solid, mature footballer.
I note that after being all the rage in 2003-2004 he was basically out of rep considerations for about 5 years until he moved into the forwards.
Who decided to move him into the forwards? Was a bit of a masterstroke imo, all of a sudden a solid but unspectacular back becomes a skilful and pacey forward. He obviously always had the toughness.
