Is it unfair of me to feel Brown would be a safer bet than Walker? I feel like both could potentially disappear in the games and not contribute or help greatly but that Walker would be more likely to possibly 'hurt' by making a mistake.
Of course, either could be complete failures. However, it would be grossly unfair to single them out (not that that's going to stop anyone), because if anyone has disappeared in recent weeks Kersten has.
Depends what they want, if they want a forward who can assist in the ruck if required they may go with Walker. If they want a forward who can assist in the backline it might be Brown.
