well they will have to now give mitchell a decent pay rise for head coach, so that is extra. Plus they will have to pay extra for a new vfl/line coach, out of the soft cap, so it will definitely hurt them in 2022.
however, there may be a clarkson payout clause whereby if he takes on another coaching job in 2022 his payout for 2022 is reduced according to some agreed formula? It has been done before.
