The 80s heavies were very talented..what gives them their rep is so many of them fell victim to their vices and or bullshyt. Buster was far from a bum. He had physical talent for days. His problem was just he had problems sustaining motivation and effort. It was all mental with him.
Boxing wasn't his passion. His pops pushed him to fight. He was a natural but wanted nothing to do with boxing. Apparently he was a great basketball player.
