Look i am sure flash is good and all but he is pretty overrated i mean he was ranked so high on the pound for pound before really beating many guys. He may of been gifted but in the last fight when he got owned and taught a lesson and had no plan b didn't seem so great. That would lead me to believe he has athletic gifts but if he can not adjust and know how to win if the guy wont engage then i would say he is not as sound. I would say Spinks, Leonard, Hearns, Jones, Mayweather, and Ali have more gifts. The list of fighters more sound and able to adjust and box would take me longer to list so i will stick to that for now. I am not sure were you came up with the idea but it is sure a different opinion. You also have your points but his list of fighters beat aren't even close to the ones mention either so its kinda hard to judge.
