To be honest, if we had a decent half and five eight we would only need a stable hooker to give good service and defend well.
If our 6, 7, 9 is Maloney, Pearce and Hinch, then 9 in a row is almost a certainty no matter who our fullback is as they simply won't get any ball. If we instead go with a spine of, say, Hayne, Sezer, Reynolds and Hinch, then you've got an organiser in Hinch and Reynolds and two dynamic ball players in Hayne and Sezer who would add the spark.
The issue, then would be picking a strong forward pack that plays in their right positions.
Of course, all of this is said in a fantasy land where form and common sense prevails, so it is likely we'll end up with:
1. Stewart
2. Hayne
3. Morris
4. Jennings
5. Morris
6. Maloney
7. Pearce
9. Ennis
14. Gidley
... resulting in us getting royally pumped.
