Don't envy the club's dilemma with this one. Could very easily come back to haunt us, but then again I don't think there was ever an obvious answer.
On the one hand, he clearly doesn't have the natural attacking talent that any of our other wingers do. Doubt there'll be any other clubs with 5 first team wingers, and it's not fair on the lad if he's not playing.
Having said that it's rare to get a winger who is so good at the other side of the game, running the ball from his own line and doing the hard yards, at such a young age. You see the work that Richards/Hall/McGilvary/Makinson can do for the team when they're in their late 20s, it's a real asset and there's a chance that Davies could develop into one of those wingers (perhaps not quite to the same level).
We can't keep them all, and this might be the best option, but Catalans have been canny to sign him. If I were Leeds I'd have been all over this.
