If we're going to have Moses or Norman in the team, then we need what I can only describe as a calming/settling/organising influence as their halves partner.
Salmon may be that half one day, but he is only 19 and outside of Cleary and Pearce, very few young halves (under say 22 years of age) have been able to perform consistently in the NRL in the last 15 years. I'm sure it's no coincidence that both of those players fathers were also NRL players and coaches who would have provided excellent daily advice to both players.
Salmon is probably 3 years away from being the player we want him to be. I think we would expect too much from Dylan Brown to be great at a young age also.
Good current 'calming/settling/organising' halves partners in the NRL I would describe as Cronk, Chad Townsend, Blake Green, Adam Reynolds, Nathan Cleary, Mitchell Pearce, Ben Hunt, and at his best, Keiran Foran. However, most of these took a number of years of NRL experience to be able to be consistent. I'd put Moses and Norman in the creative off the cuff style of Moylan, Maloney, Shaun Johnson, Luke Keary, DCE, Munster, Milford, Austin, Benji. These halves might win you plenty of games, but without the calming/settling/organising influence are they going to win you a comp?
