These reasons make sense that an overweight and obviously distracted Duran was not ready both mentally and physically for Leonard 2.
The rematch should never have happened so quickly, well planned by the Leonard camp. The point is Duran was in a close fight at the time of him quitting, it's not as if he was getting well beaten such as Tyson against Holyfield and frustration got the better of him. His conditioning gave out and along with Leonards game plan of clowning about and running for the entire fight Duran simply gave up. A strange decision on his part, but so is blowing up to more than 200lbs between fights in less than 6 months.
The first fight was Duran's finest hour and Leonard had no answer to him in that fight, the scorecard flattered Leonard IMO.
Why was there no rubber match in 1981?
