Agree with all your points. Malaysia has good talents but BAM has been facing leadership and management issues since years ago. Unless BAM and their coaches improve the management and leadership, MAS will keep producing inconsistent results. I feel pity for the players.
I think Baminton in Japan has vast room for improvement too. If they can attract a few more talented coaches to form a bigger coaching team to take care of their young talents, they can be a strong force to be reckon with. Japanese players are disipline and have strong fighting spirit. These are already good ingredients for success.
