He's not worth that money, has as bad a judiciary record as Hetherington and is injured all of the time.
He's a solid player who's aggression can be good and make an impact, but not at that price or age.. Would you rather offer Taumalolo or Haas a million in their prime or Brown 600k at the back end of his career? Would you rather offer Brown 600k or Pangai Junior 650k? As others have said, there's a reason why clubs aren't giving Brown what he wants.. Because he's not worth it and there's better value elsewhere..
