Ghost inducted in a hall of fame

It is still mind blowing how on Earth can Sylvester Stallone a.k.a. "Rocky" be inducted in the International Boxing Hall of Fame. As we all know Stallone is an actor, he has never fought a single real life match. Rocky is a fictional individual aka Rocky does NOT EXIST, he is a FICTION, how can a non existing person be inducted into a prestige place such as the International Boxing Hall of Fame is beyond me.
