If Zion reaches Barkley level he will truly be an all time great. Barkley, for his physical build, was an absolute freak. His athleticism, his skill, but more than anything, is drive are unparalleled IMO outside people like MJ, Kobie, LBJ. Sir Charles was a beast and and player of the highest order. Way above, IMO, opinion guys like Reggie, Karl Malone, or Ewing from his general time period. All those guys were great. Make no mistake. But I always found Barkley on a different level.
