There might be some confusion regarding which "Billy Thompson" you are referring to, as there have been multiple basketball players with that name. Assuming you are referring to Billy Thompson who played in the NBA from 1986 to 1992, it's difficult to provide a direct comparison to a current or former NBA player due to the vast number of players and different playing styles. However, during his time in the NBA, Billy Thompson was a 6'7" forward known for his versatility, athleticism, and defensive abilities. With that in mind, one could possibly compare him to someone like Andre Iguodala or Trevor Ariza, who are both versatile forwards with defensive prowess and a balanced overall game. Keep in mind that these comparisons are not exact, but they provide a general idea of the type of player Billy Thompson was during his NBA career.
