Off the top of my head:
Howard
Houston
Byrne-Jones
Clurey
Bonner
Dixon
Jonas
Polec (hence why he’s getting a monster deal from North)
Howard, Houston, dbj, clurey and bonner have barely been on the list 4-5 years you would hope they have improved.
Dixon is no better than at gold coast.
Jonas got worse and then improved.
Polec left brisbane when it was a basket case. He has improved mainly because he was unsettled and unprofessional in brisbane. He hasn't improved as much as yeo and docherty who left at the same time.
The problem is our system not even our development. Other teams are better drilled. Other teams adapt better to different tactics. Other teams play some sort of structure, a ruck and a forward line. It's not hard to imagine that the players lose confidence when they have nothing to kick to. The problem is our coaching and the buck stops with hinkley.
