The Miller question is dependent on the goal kicking question for me.
If we line up like this as an example..... there are variations with the same team.
1) Hall
2) Owen
3) Collis
4) Lyne
5) Riley
6) Sammut
7) Smith
Anderson
9) McShane
10) Scruton
11) Kirmond
12) Ryan
13) Washbrook
14) Godinet
15) Paea
15) Kirke
17) Ali
For Miller to play, Sammut has to move. If Sammut is the only goal kicker, he can't move out, only to another position.
His only other position to speak of is fullback.
We are hardly likley to not want to play our new signing so that knocks on to the centres.
For me, Owen is the weak one (barring injury to Collis) so Lyne moves out there.
It's a nice issue to have but someone is going to be disappointed.
