The core:
1. Dugan
7. Pearce
9. Ennis or Farah (choose one and stick with it)
13. Lewis
Once that core is built, the next step is picking the centres and props:
Idris or Lawrence for the big, line-running centre spot
Jennings or Morris as the strike centre spot
Mannah and Galloway as the explosive props
Snowden and Douglas/Tolman as the workhorse props
Once they are done, work on the backrow and wing spots:
Watmough as the linebreaking backrower
Heighington as the workhorse backrower
Gallen as the bench backrower
Bird as the utility backrower
Hayne or Gordon as the speedy, supporting winger winger
Uate or Morris as the big aerial target
That only leaves the five-eighth in question - Sutton or Campese or Carney or Mullen or Soward. Plenty of options, but they need to find the most consistent player to compliment Pearce.
There you have a decent team built from young talent, with experience in just the right areas.
