No way. If you look at the way he had to come up in boxing then you'd understand. Both he and SRL had career's in parallel, except SRL had everything handed to him. Remember watching a good doc on it and I think that Hagler beat SLR as an amatour, and because of bad luck and management their career's took different paths. Hagler had to earn his shot fighting through the clubs and undercards. The most pertinent point was that after SRL won his olympic gold and turned pro and had his first fight. He was being paid loads and headlined the card. His first fight as a pro. Guess who was apparently way down on the undercard! Hagler! After fighting loads of fights as a pro already, to be paid peanuts to fight low down on the undercard of someone in their first pro fight, and having already beaten them.
Hagler always hated SRL because he saw him getting everything that he didn't, including the addulation and respect for his boxing ability. So to actually loose to him in the ring, when you truely feel that you won and had been robbed was the final straw!
