Just don't have Cust defending in the middle. For all his good points, Cust's defensive game reminds me of James Maloney, not that good. Oh he'll pull off a few good tackles, but he'll miss a few more.
I think that's why when Fainu went off Des opted for Croker at dummy half and defending in the middle of the field. His defensive game is better than Cust's.
Docker-clay played in the halves for Blacktown in the 2nd half, and defended in the middle third.
It is certainly an option.
