In addition to possesion etc, the other thing needed is field position, more so now with the new 6 again rules than before.
In the 2000s field position used to be a big part of our game, and part of the dominant qld sides, with lockyers boot (in origin locky, thurston, smith and cronk) often keeping us in games despite being beaten in other areas.
Because our defence is poor we can rarely defend our line so it is important we play the game in their end of the field, but because of our predictable kicking game and passive line defence we spend most of the game in our own half.
Although we had the passive line defence in 2015 and 2016, our goal line defence was solid enough to hold out teams and we could score from anywhere on the field (which we cant do now).
