Everyone is making good points here.
North Queensland fans are justified to defend Ray Thompson. He's a local junior, displays tremendous attitude and work ethic, defends stoutly and has displayed glimpses of a promising attacking game. Fair call he's not developed at an express pace, but many Cowboys fans feel he'll be a slow burner and that aspect of his game will come along eventually. Time will tell, but there's every reason to be optimistic.
On the other hand, Lui is a natural playmaker, and it took him no time at all to settle into first grade. He's got fabulous hands that compliment his passing game, and I like the way he moves across the field, it troubles the defense. And there is a point to the argument that, for halves, defense is a secondary priority. Now without going into the his personal life, I can see why the Cowboys wanted him.
Cowboys fans are right to praise Thompson, likewise others with Lui. At the end of the day they are vastly different players and both can bring something to the club. Of course I say all this without regard to an alledged crime that is said to have been committed, which is another matter entirely.
