The most devastating KO was Norris getting splattered by Jackson. Jackson had scary power.

The funniest and most satisfying is Kostya's over Zab.

Hearns - Duran is classic. What a right hand. Devastating. But it was a blown up Duran. Not the most shocking but considering that Hagler had just taken him 15, then it is a bit shocking. Awesome right hand.

Frazier - Foreman though is the most significant of all.
