Did the Heavyweight division eventually lose its way?

For me the heavyweights was always the glamour division,however,I felt by the 1980's it had lost its sparkle.By then,for me,the exciting bouts had become the heavy middle/light heavyweights.Bouts that featured Jones,Rocco,Dynamite Kid,Finley,Kung Fu,Fuji Yamada,Chic Cullen,Rocky Moran and there's others I have missed off .All hard,fast skilful bouts.Some of these bouts were breathtaking.Your opinions please.
