Well, for one thing, he would have continued his career I tend to think that he would have been beaten pretty easily in a rematch and that he might have either hung it after that or stayed around as a solid "name" opponent for up and comers. I remember his fight with Toney well, it was an outrageous robbery, one of the worst of that era. Clear win for Tiberi and the judges stole it from him. Sad.
