It's gonna be a tight call between Scott Williams and Jon Davies to start against Fiji and Ireland in the quarters (if we get there). They are both similar type of players, physical with a decent turn of speed. I disagree slightly with peoples comments about Jon Davies in this game, because I thought he put in plenty of nice little touches, with some great little take and gives to release the man outside. On some occasions in the first half, Namibia's defence was up very quickly, and I thought Jon Davies did the right thing hanging onto the ball instead of shipping the ball onto Halfpenny etc. to get smashed. He had a hand in many of the tries today, and showed good pace to finish his try off. Scott Williams was also superb, and thoroughly deserved his hat trick of try's.
I agree that Jon Davies hasn't managed to translate his excellent Scarlets form onto the international stage yet, he's shown glimpses, but he's also had some terrible games. He's steadily improving, but maybe Scott Williams is overtaking him. I don't think Regan King is the reason for Jon Davies' improved regional performances, because King has been injured for a fair chunk of Davies' rise. Davies and Maul played quite allot together, and most people agree that it was in Kings absence that Davies really matured as a player at that level.
As to who would work better with Roberts, that's an important question. Roberts is in great form, so he's gotta play. I've yet to be convinced with the Roberts, Davies partnership, no matter which way round they're played. I don't know why, because if Davies could get on the shoulder of Roberts, his finishing ability as shown at the Scarlets is very good, ditto the other way round. So in theory it could work, but in reality it has failed to gel properly. Maybe a Scott Williams, Roberts combo would work better, only game time will answer that.
Very interesting call, which could get even more interesting if/when James Hook regains fitness.
