The reason Hagler-Hearns is such a standout for the ages is that it had the build-up of a LH-Mayweather/Mayweather-Hatton in an age when boxing was on free TV and consequently recieved much more attention in the press/boxers were much more well-known etc., but then the fight lived up to the hype.

It wasn't a DLH-Mayweather kind of fight. It was the fight the public had been built up to see for months. It did exactly what it said on the tin.
