We're going to have to cut corners though to afford both of them and probably Dangerfield and Dunkley assuming they’re M/F dpp's again. Those four alone are guaranteed to wipe out over a quarter of the salary cap. Full rookie defence line sound alright mate?
3-4-2-3
Docherty , Mitchell & Ward could be the keys , a few cheapish rookies that didn't play this season (eg Rankine , King) , heaps of value (possible traps in the F lines)
2 @ $ 700k = $ 1.4 million
10 @ $ 625 k = $ 6.25 million
Bench = $ 1 million
so 10 players for $ 1.35 million + the savings from Doc , Titch & Ward might allow a 13th premium
but yes will all depend on where the rookies are Round 1 , hopefully Rowell & Anderson are ready to play.
