Barge Arse, not sure if him raising to another level or just that he ended the year on an edge where he was more involved in play, when he was at Lock the emphasis was on Defence and covering for others defensive deficiencies.
Professionalism and experience is something which needs to be bought into by the squad, while it is good to have direction from a team mate it means nothing if players think they are better individually than the team.
Having a team functioning as it should does allow a player to perform , within the structures that suit the Game plan, successful teams have specific parameters each player is allowed to operate within, when an individual doesn't adhere to these parameters , disciplined players often show adverse effects of uncertainty.
Brown should have a plan with specific parameters for each position rather than each player, some players are capable of playing multiple positions therefore logically they need to be disciplined enough to operate inside the parameters set for position on the field, often these will dictate how much of an impact they have on a game whether the emphasis is attack or defence , this often alters from the punters perceived expectations for each players week by week performance.
