Has to be Kimmorley, Preston, Bird, O'Donnell or Watts.
Watts is 23, so unless they've offered him a nine-year contract to "finish his career with the Sharks" I can't see it happening. The article scared the hell of out me til I read that.
Kimmorley is past his use by NOW, let alone next year. O'Donnell is looking for his last contract, but you wouldn't exactly call him a complete footballer - he's just a tough-as-guts second rower who knows the middle names of every member of the judiciary. They already have Gallen for that.
Which leads me to believe it's either Preston or Bird. Hmmm, interesting.
