We can't go overpaying Kelly; it creates a burden on the TPP not unlike overpaying Fyfe (although, with less risk due to no injury history). If North want to give him a ridiculous offer, then let them. All we can do is offer what we believe to be fair for him and our club, and then look at all other opportunities while waiting for his decision.
It'd be like scrapping over the last Snickers in a supermarket, with the other bloke offering $10 to the shopkeeper. Just because you want it, doesn't mean it's worth paying $12 - just buy a Mars for $2, a handful of peanuts for $4, and use the rest to grab anything else you could want.
