Great job by that young lady keeping her head about her.
This is a question he hates and he is sick of. Because he is as big a student of boxing as any fighter ever. Without his demons, he would have had a long wonderful career as a analyst, because he knows more about boxing than 99% of boxing media.
Because of that, he knows his legacy is what Tom and I said. He knows he isn't the best ever, or close to it. He knows he doesn't have a proper legacy of an all time great. He knows maybe he could have, or maybe he knows deep down that he never had it. But its's a very unusual situation for the subject of evaluation to be basically a historian himself and have a brutally frank assessment of his shortcomings.
