To be honest, from the 1980's, who were the really good men's singles players? Zhao Jian Hua, Yang Yang, Sun Jun and then Lin Dan. In the 2000's, MS did get stronger as did the whole team. Why? Because of Li Yong Bo? Indirectly yes because he brought Tang Xin Hu into the coaching staff. I don't think it is a coincidence that this present generation have not been under Tang. That lacking part is the retirement of Tang from the national coaching setup. Surely not just a coincidence....?
