I'm confused and can't see why we can't emulate the Warriors standby team.
If Moore wants Holdsworth, then keep him benched as a potential second rower (which he has played this year before).
Stagg in the halves, Eastwood/Warburton (with his new found attack)/Gordon to lock.
END RESULT:
+ Second Row loses little impact as we still have some good players on rotation there (with Holdsworth if required).
+ Lock retains it's defence and attacking spark.
+ Stagg talks on field and can get the ball out when required, not to mention he has a long range kicking game, AND will harden up the defence on Idris's side.
Sure we lose a little bit of defence from Lock, but shouldn't be that big a difference. Besides Gordon carving up the centre of the field. YES PLEASE!
