I would imagine AWJ would have been one of his first picks. He is an awesome captain and I would imagine the coach would be after someone he could trust and has confidence to lead. AWJ ticks those boxes, so even if others were ahead of him on performance, his leadership probably swayed the decision.
Clearly I have no idea, and the reason may have been his name was drawn out of a hat, but given what has happened with Wales since I suspect not!
