He didn't say dump him, he just laughed...
Look at things fromn the outside (of Australia) - endlessly we get these stories of players who would be international greats if they weren't Australian etc etc... or are supoerbly talented and wiull dominate once they get their opportunity
In recent times - Hodge, Hussey, D, Krezja, Hilfenhaus, Bollinger, McGain, Rogers, Jaques, White, North, Ferguson, Haddin, etc etc etc with Hughes being the latest...
Then we see them in international cricket and they range from crap to merely decent cricketers... no doubt Hughes is a talent, but you have to admit that was a comical debut after all the beat up around him
