In 2017,JJ wasn't selected or didn't play lock,Tyson Frizell did.
That's why during the World Cup selections,JJ was being compared and missed out to Cordner,Graham,Kaufusi or Gillett and not Trbojevic,Frizell or McGuire.
NSW since 2013,have always lined up with 2 props and a ball playing prop as lock,Gallen owned that position for years.
The style Laurie Daley used for NSW in both attack and defense did not have 2 distinct edges like we are used to in club games.
The style in defense uses a flat high right,a streched V and a traditional left edge.
Reason for this style is to push Queensland back inside at 4th man (the right 2nd row),to keep the middle very tight.3rd and 2nd man rush up beyond the 2nd rower,in case ball is pushed out,with wing for cover.The 5th man in (the lock),at the high point of the V must be strong enough to be able to achieve ball and all tackles and stop 2nd phase play.
You need your best mobile grass cutter at 4th man do this job effectively and that's why JJ got selected in that position for NSW.
With this style,NSW limited Queensland in using their fullback and 5/8 in exposing the area between right 2nd row and center.It also reduced the ability of their interchangeable spine to stretch the middle and attack the outside area of the props.
Trying to hold 1 line and slide across field is suicide against a talented fast interchangeable spine,when any of the 4 can run up beyond their forwards and up to the advantage line.It would have been over after game 2.
In attack,the hooker joins the halves,the lock and right prop move one out,with the right 2nd row lining up instead of the right prop.
This style uses the wing,center,lock and prop to run the ball up from inside NSW quarter and the lock,right prop,right 2nd row and left prop to bombard the right edge (Queensland's left),in the middle second.Each forward should only carry the ball once per set to reduce fatigue.
Reason is to condense the defense towards the right and more importantly loosen the middle.Once this is achieved,the halves will have no problem finding gaps for themselves or put the fullback or left prop through.By counting numbers,they can decide to spread the ball to the left edge on the 5th or 6th tackle.This is why Pearce and Maloney ran through gaps and scored 3 tries between them.Fafita and Tedesco both had a huge game 1 with both scoring a running try through the guts.
With this style in 2017 NSW scored 5 tries in the middle,3 on the left and only 1 on the right from a cross kick.
Brad Fittler's coached teams,NSW-City and Lebanon have played with running line breaking edge 2nd rowers and an old school lock.
NSW has numerous on form,very good,line breaking,running 2nd rowers and with De Belin on fire and permanently playing lock,it's going to be very hard for JJ to get selected in either position for SOO this year.
JJ is not an impact attacker,but does have a decent all round attack,good hands and is an energetic decoy and chaser.Origin is tailor made for JJ because of his 'never say die' battler attitude.If his form improves,his experience and reliability in defense might earn him a spot in the NSW squad for 2018.
