Historically speaking, is induction into the International Boxing Hall of Fame, known as boxing's greatest honor, a substitute for not winning a world title? Sam Langford, Sam McVey, Pedro Montanez, Laszlo Papp, Packey McFarland are some notable fighters without a world title who enjoy Hall of Fame (IBHOF) immortality in Canastota. So has the sport forgiven them for not winning a title? Also, if the Hall is a substitute, then is it the only one, or is there another substitute??
"Substitute or Forgiving" are hardly the right words, though I know what you're trying to say. It is neither! They are a place where Greatness, Near Greatness and Credible Worth find an Historical Home. Time can be a great thief and Champions weren't always the best fighters of that particular division or of that particular time. Champions, the best ones or not, got the Coverage, the Press and the History... but Hundreds of Great Contenders, Ill-Fated Campaigners, Cheated Fighters and Forgotten & overlooked men too often got very little in comparison, this is what Halls of Fames give back. But even the Halls aren't perfect, many will still be overlooked, but at least it picks up where History stopped, so to speak. the Substitute, that you mention, is probably the Peoples Champion, in that during the course of certain Fighters reigns the majority might have felt one or two others were really the True Champ or Better fighter, but even those sentiments can get lost to Time. the Halls are a good thing, Boxing History has thrown up thousands of great fighters, thousands of them.
What does a title mean now when Mikey Garcia, who is a good fighter can win 4 at this early stage in his career. He is not qualified for that. I could see at this point one title and working on winning his second. Not 4.. So titles now mean nothing. Hagler just made a statement how they should just have one title.. Obviously that is wishful thinking, but boxing would be great and the title contenders would be hungry for a title shot since they would be rare.
