I have never been a big believer in the concept that a fighter needed to be a world champ to be great. There are quite a few fighters who never won belts who in my own mind ( and not necessarily anyone elses, ) will always be great. Here are just a few names : 1. Jerry Quarry 2. Sam Langford ( won colored world title, but not lineal ) 3. Harold Brazier 4. Roland Lastarza The list goes on and on. If Frank Bruno hadn't won a title from Oliver Mccall in the 90's I'd have him in there to, but as it stands, he only improved his legacy by becoming a champion, so more power to him. anyone else want to throw in some names?
Jack Chase. Never won a world title, but was seen by many on the west coast as the uncrowned champion of the great 1940's MW division. Beat some great, great fighters. Be a millionare were he fighting today.
Lloyd Marshall didn't ever win a title did he? And I'd pick him to cause a lot of top ten guys trouble in 168 and 175.
Good pick, Chuvalo was tough and had some very good wins over some talented fighters. I have to put him on my list to.
Ezzard Charles never won a title at light heavyweight, but he's argueably the greatest 175-pounder in history.
