Gee, it's a nice problem to have though, isn't it? Working out where to fit a star in to the betterment of the team, as opposed to where you can dig up quality players in a position.
If Beale does go back to the Tahs, there's only two options for me: a) Beale at 10, Folau 15, Foley on the bench, or b) Foley 10, Beale 15, Folau at 14 as the second fullback.
I love Folau at 15, and I really like Foley at 10. Foley at 10 offers a good passing game (which can be wide), and a running threat. Hopefully Foley's game management will improve, and because of this and the current make up in the centres I would lean towards b), despite loving Folau at the back.
Beale is a different sort of 10 from Foley, as I think Beale's long passing game isn't as good but Beale will follow the ball more looking for that second touch and space out wide. I currently think that Foley's game is more suited to Horne 12, AAC (Adam Ashley-Cooper) 13 than Beale's style. I would think that maybe a 12 like Lance would fit the structure more than a 12 like Horne.
Additionally, in option a), Crawford would be my pick of the second fullback.
Either way, it's a nice problem to have, and either selection (Foley or Beale at 10) can be perfectly well justified.
Lance is a good signing from Cheika too, with the loss of Barnes the addition of Lance maintains a good depth in the squad. Lance can cover every position in the backline bar wing at a pinch - I'm sure Lance covered 13 in a game for the Reds. (Although that game is better not spoken about.)
