I certainly don't think Tyson was the greatest of all time, was just repeating a comment made by a boxing fan who's only knowledge was Tyson!
Certainly Tyson was a great fighter, but I think made even better by the lack of real competition at the time. This is not a reflection on him because you can only fight what is there. He was a devestating puncher hence the reason for that many fights in a year. I'm assuming they were very early on in his career and he was blowing away lots of part-time journey men in the first few minutes of the first round while not taking any ounishment himself.
This is the way of most good fighters early on.
I have no problem with people wanting to learn about the sport, we all did, just those who claim to be experts but don't know anything. I do distinguish between boxing fans and fight fans. The later just want to see a mis-matched blood bath and will be booing at a technically superior fight within the first 2 rounds. For me the performance put on by PBF against Baldomir was a boxing clinic, but there are plenty who would disagree with me and say "he ran", "was scared" etc.
I would never call myself an expert or think myself suitable "to teach" other's about boxing or its history. I myself am constantly learning from those here, but am just frustrated by not being able to have a half decent conversation about boxing. This forum is a god-send.
