There are several unsolved mysteries in Gan Guoyang's career.
For example, in the 1984 Christmas game against the Rockets, who threw that punch?
As time goes on, the significance of that punch has been increasing.
Because apart from that, you can't find any instances of Ah Gan getting hit in the NBA.
Another example is the overtime three-pointer against the Bulls in the 1992 Finals—did he step on the line?
Without high-definition camera replays, this shot remains controversial, but in the end, the Trail Blazers won the championship, making this question irrelevant.
Anyway, Gan Guoyang always said he didn't step on the line; it was just the shadow of his shoe touching the three-point line, and the referee was overreacting.
In the 1992-1993 season, another mystery in Gan Guoyang's career came from off the court.
Michael Jackson claimed in an interview that Gan Guoyang was the most talented dancer he had ever seen among basketball players.
