If you've all done your homework you saw a young Duran do a Henry Armstrong imitation to beat Ken Buchanan. His head on Buchanan's chest, endless punching and savagry and some wild moves.

Now you are going to see Duran fully developed more than five years later. Esteban DeJesus, ranked #1, is the only man to beat Duran and though Duran won the second fight he was on the deck in each one. In each of those fights Duran pursued, Esteban countered. Now watch Duran out counter the counterpuncher.

Duran's talent has now been complimented by Ray Arcel's and Freddie Brown teaching him skill and imparting, and Roberto absorbing, almost 100 years of accumulated Ring wisdom. The movements are more efficient, his approach more measured and yet the ferocity remains. For those who have the image of Duran as brawler? Prepare yourselves!
