THe South's game was an example of playing two 5/8 in the halves.
It resulted in no depth to our attack, no organisation and a rubbish kicking game.
Luai is the best 5/8 at the club by a country mile so that position is his when fit. He is yet to have the benefit of playing with a proper half back at the tigers.
Luai when partnered with a proper half back has 4 rings, State of Origin victories and Victories with Samoa.
AD isn't a half back. He is a a strong runner with an improving passing game. His kicking game is rubbish. Can't organise the attack let alone provide depth. He also tends to be sideways rather than straightening the attack.
He has operated as a 5/8 in every game this year, put what ever number you like on his back but he isn't nor ever will be a half back.
He needs to be in the team but should be humble enough to play where the team needs him and not demand to play where he wants to play.
Jock is a half back and by your definition he's been winning so should stay in the team.
