My pick is Rajon Rondo. He somehow manages to slide his way into conversations about the best passers of all time, or the highest BBIQ's of all time, or top 10 PG's of all time (I've seen him go as high as five) seemingly on account of a single championship that he was the distant 4th best player on and a 44 point playoff loss (where he only scored those points because he was intentionally left completely wide open, which should say something).
I've even heard people say that he outplayed Lebron in that 2012 series

What are your picks? Can be from any decade.
