Probably Dame.
I would say Harden but in terms of him throwing a temper tantrum to get his way and go to a winning team that ship sailed a few iterations ago.
Dame wins a chip and he jumps to the next level in terms of legacy, right now he's kinda in that Clyde Drexler / Dominique Wilkins / Tracy McGrady Tier.
I knew I'd miss something like that! I always forget he was a Rocket.
