In all fairness, Tyson's true reign as lineal champion, was during the late 80's. During this period he met all of the above listed criteria that CT asked for: 1. He fought all top contenders 2. He defeated the recognized lineal champ(s) 3. He held all governing belts. You can argue that he didn't face all the best fighters of the 90's, but then he wasn't exactly viewed as the lineal champion by this point either.
You're starting to look a little silly now, just disagreeing with me just for the sake of it. The two posters above seem to agree with my pick as they have slightly more intelligence and realise I was talking about Iron Mike Tyson (his first incarnation pre prison as lineal champ). Though I suppose they have nothing against me and are able analyse my posts impartially. Take heed brother, take heed.
??? LOL... All joking asside, this is a good thread and there are a lot of good responses from everyone.
Don't worry brother, I'll teach you. You can be my student. I'm always happy to school you. Just remember to call me Sir
Armstrong may be the best single example, since he defeated EVERY top fighter in a specific time frame and weightclass range decisively, holding all of the belts in the process after nabbing them from linear opponents.
