Either way, I am reasonably relaxed on the whole matter. Cuz or Gourdis, both are risky. Drafting Cuz doesn't prove that he will work out - if that was the case he'd be at Collingwood, Lions, Saints or even Essendon.
We'd still be waiting at least until the pre season cup or even Round 1. Even then, if we'd seen him at the top of his game, you'd still be wanting 2-3-4 months without the strings going ping before thinking he was on his way.
