You’re saying there’s no plan B if he got injured ?
Young guns stood up when trusted with the assignment against Penrith & Dragons. Belief goes a long way.
You know that is a different scenario entirely. Your cap is still invested the way you planned, you still have a squad you have engineered.
Sure if Cleary, Ponga, Hughes, DCE etc get injured a team can put in a plan to bridge the gap. Their clubs would be in a funk if if one of them decided to upsticks in January too. In longer term succession planning, and sustained success over a season(s) you need your big dogs to be accounted for - many a team has had their season derailed by losing a key player they can't afford to lose.
