The short answer is no, Hagler fought legends which enhanced his legacy by taking on Duran, Hearns and Leonard.

Duran was the first fight for Hagler where he received huge money and mainstream attention. Roberto went on to become champion when he beat Blade Barkley.

The Hearns fight was built for ages and Tommy went on to higher weights to become champion. It also provided the greatest 3 rounds ever.

Whilst he may have lost to Leonard he had the last laugh when he stayed retired to the frustration of Ray. Leonard went on and got embarrassed by Norris and Macho Man.
