Zo used to be one of my favourite players when he was on Miami (the first time). He was an undersized center who protected the paint like few others, and was dependable for a 20/10 every night.
With that said, I don't know if he should make the hall save for the 'sympathy vote.' He was on his way to a hall of fame career but IMO he hadn't earned it yet. His top-seeded team was repeatedly trounced by the Knicks in the first round of the playoffs, and he had some great teammates (it wasn't like KG carrying a moribund Minnesota time and time again).
Right when Zo was perhaps going to turn the corner and start taking his team deep into the post season, the whole kidney issue blew up.
