However, through a combination of fortune, skill, and ingenuity, he holds that line for ten straight years, eventually coming out on top single handedly. Now he has to tackle the dilemma of how to occupy himself in a world where he holds a myriad of roles: that of a legend, that of a veteran, and that of a brand new face.
