I am going to propose a highly theoretic question. If Sun Jian had not gotten killed, then who would he have served as he did not seem to be a warlord, but certainly had the ability. Also, if he did serve someone such as Yuan Shu, would that leader have lasted longer, and if that rulers demise came while Sun served him do you think he would have went to Liu Bei or Cao Cao in the end?
As for me, I think he would serve Yuan Shu, but notice he is not being put to his best use and went out to either serve Cao Cao, who would actually use him, or start his own kingdom as he had the generals already.
