Just remember that Griffin has come out wanting Bird in the squad. So if he does sign and all goes to $hite, watch how Millward will cop the blame.
If you are going to buy a player like Bird on potential (like Saints did with Norman), then they should take a punt on Bryce Cartwright as I am sure he will come much cheaper than Bird. Personally I would not take a risk on any of them but if I had a choice of Bird or Bryce I would go for Bryce only because of the $$. Paying over 600k is ridiculous for Bird. I think Saints can probably get Bryce for 300-400k and maybe offer 1 year (with an extension of another in the clubs favour) only to see how he goes.
