Playing him off HB makes a massive difference for Houli and Ellis who will both be he beneficiaries of the attention he will get if fit and firing.
Also, our style of play out of the backline should work ridiculously well for him personally. Look how much space our release defenders find already and none of them have the wheels this guy has. And one other important thing is we have Rance, who creates more turnovers than anyone else in general play and when he breaks and runs all of a sudden there will be an option not only able to keep up with him but exploding past him. Rance causing a turnover and releasing Yarran through the middle of the ground with the opposing team's defence out of position could become dynamic over the next few years.
