So Duran beat Leonard because Leonard had an off day? When Leonard tried to box Tommy he was getting beat. When he changed gears and went into the trenches against Tommy, ala Montreal, he stopped Tommy
The point is Duran was a better in-fighter than Ray and Tommy was better on the outside, Ray used an active guard v Duran in the rematch, his feet never stopped moving, Ray was far too static in Montreal, Duran was an amazing in-fighter and Tommy`s jab was something else.
Leonard was a great infighter as well. Everyone knows that. His all around game was amazing. He just got beaten that night by the smaller, slower, older but better infighter that night. It's that simple.
