In my opinion half the problem is attitude. Line speed, aggression, kick pressure, support play, all those 1% EFFORT plays that require no skill only attitude.
AOB has fostered an environment where players feel their selection in the team is never under threat.
Yes this can be put down to poor recruitment and retention ( no depth in the roster ) . But if a player is not putting in EFFORT , replace them with someone who is putting in EFFORT . Yes there will be some losses initially, but long term it sets standards within the playing group.
