I'd rather just pick the best halves pairing and go from there. Anyone playing 6 while Moylan is at FB is just going to be a passenger not getting the kind of ball halves would usually get or need to be effective.
Maybe, but if you look at the number of touches that halves and fullbacks get in other teams it seems that besides dummy half (always the most touches obviously), the number of receives at fullback is surprisingly high. It seems in some teams the fullback gets more touches than the 5/8th or halfback. Coote often gets more touches than Michael Morgan (excluding kick returns) and this is reflected in their attacking structures where Coote plays like a second receiver for many plays.
Against the Cowboys Darius Boyd had 45 receives (plus two kick returns) and Milford only had 29 and Ben Hunt 41 receives. Against Cronulla, Munster had 24 receives (plus four kick returns) against Green's 30 and Cronk's 38. A relatively even number of receives. Cronulla were the opposite. Barba had less than half the touches of Townsend and Maloney.
To me it just shows that who is the play maker depends entirely on the make up of the team, not on the position. How the game flows on the day seems to also have an impact. For example, against South Sydney Thomas Leuluai had more receives than Shaun Johnson (a supposedly dominate halfback). Against the Gold Coast, Shaun Johnson had 50% more touches than Thomas Leuluai.
Against the Roosters, Cartwright had 42 receives and Moylan 25 (plus four kick returns). Against Canterbury, Moylan had 44 receives (plus six kick returns) and Cartwright only had 26. I thought this was an issue as well, but it turns out when you look at the data, there is simply no hard and fast rule and I don't think it makes any difference where Moylan plays in terms of playmaking. He demands and gets the ball when he wants it. In some games he touches the ball more than any other player, some games he doesn't.
Other teams are also successful with a fullback dominating, or a half or a 5/8th, or an even share. The players just need to communicate and train to encompass all three playmaking positions to avoid confusion on match day.
I think the only issue with Moylan at fullback, as I have said before, is his kick returns. They are weak and the only bad point in his considerable range of skills (he drops a few bombs as well, but not enough to consider it a major weakness). That said, we have two beasts on the wing who more than compensate for his lack of metres on kick returns and the coach has them dropping back to bring the ball back to offset this. Problem solved.
If the coach leave Moylan where he is, we may well find ourselves in a position where we actually have four playmakers in the team with TMM,Cleary, Cartwright and Moylan. That could potentially be attacking nirvana and a nightmare for other teams to defend against. Roll on 2017........
