Clarke > Nic Nat
Good discussion topic though. I would consider Hurn and Kennedy.
The one thing that excited me about clarke was hearing RTB (i think on SEN) saying he has started to apply himself during the week mentally and to learning the game. That he has been good physically but has added to that.
Lets hope that with a run of good health we see consistent improvement.
I would more than consider hurn and kennedy... both seem like decent types too... well at least compared to most of their team mates!
