Grundy would lose his Superpowers if he moved clubs
Why not and good on him, sacrifices come in many forms and to win GF's you need to make some. Not that a 7 year deal at Collingwood is a sacrifice, just the $'s.The consensus among observers seems to be that he is going to be earning less per year than what he could command from other clubs, but he wants to stay at Collingwood long-term so will compromise on money.
