I expect we'll probably be able to retain Tizzano on a shorter deal, but it'd be hard justify more than 600k right now, and that probably needs to be Twiggy heavy. He seems pretty committed to pushing for the Wallabies spot so it might be enough to retain him through the world cup and push the decision down the road a bit. I'm guessing the offer was north of $1 million though, so he's going to have to take something like half to stay.
Might be an opportunity for a sabbatical too, it would have to be next year though, (or a longer deal to accommodate one not in the world cup year).
