Scarily similar - so the only question is whether Max can keep it going for another 6 to 8 years.
Thing that jumps out to me in those stats is weight. Very surprised that King is heavier than Daniher, not by much but I would have bet Joe had 5-10kgs on King. Joe looks a lot stronger in one on ones.
The King deal is a good move by Saints. Maybe he won't turn out to be the next superstar but he is unquestionably a guy that can hold down a KPF role and always have an element of danger about him. You can build around that and barring injury (big if) the deal will be cheap in 4 years time.
