What does it mean to “relinquish” one’s pro status? Is the idea that once you get the card you (can) no longer compete in amateur shows? Is there or has there ever been a prohibition against doing this? Why would any pro do this? What is the appeal? It sounds akin to graduating from high school , enrolling in college, then going back to take high school classes again…. Am I missing something? What’s the point of doing this? 
weird huh? i guess he felt like he wasn't getting noticed as a pro and wasn't making any money and thought it's alot more fun to win than it is to be ignored. but i agree it doesn't make sense that it is allowed. John Defendis wasn't allowed to compete in the mr. america because he was in a magazine add. i know NABBA pro's had to requalify as amateurs to get into the IFBB. Mike Quinn was pro NABBA mr. universe and had to compete in the NPC usa's. but there were other NABBA guys that weider just let in, like Bertil Fox, Brian Buchanun, Ed Kawak, etc. then Jeff King wanted to be in the IFBB, and like Quinn, he was told he would have to qualify through the NPC even though he won multiple NABBA pro universe titles. that ended his career.
