Does anyone know why SRL and Hearns waited 8 years to have a rematch?

[THE THIRD MAN]

It took him 8 years to give Hearns a rematch, the eye injury was serious and he had a two year lay off from 1982-1984, then again for 3 years before fighting Hagler.
I am sure if it wasn't for the eye injury he would have fought Hearns again in 1982 at some point. He was well behind in the first Hearns fight, he needed a KO to win and got it. Hearns people must have been pressing for a rematch. It is interesting that an immediate rematch was not called and Leonard fought again in February of 82 against former Hearns victim Bruce Finch, 5 months after first facing Hearns.(Leonard officially retired in November 1982) He was very quick to demand a rematch with Duran just 5 months after their first meeting in June 1980 knowing only too well that Duran blows up in weight between fights? It appears he wasn't so keen to face Hearns again in such a hurry? The injury eventually denied us all seeing that rematch. Leonard was never that keen on facing Aaron Pryor either? Personally, i like to see rematches about 12 months apart.
