If Harry Greb had not died on the operating table

My impression is that Greb was a speed guy. A modern day comparsian might be Roy Jones. This is just my impression from what I've read about Greb.
If this is true at 32 he would have on the down turn of his career, and would have had 3 years left to really do anything.

 

Late career Greb vs Walker vs Rosembloom, his speed was diminished put he was starting to pack a much harder punch. The weekend of his death his manager Red Mason was up in Erie Pa with little Cuddy Demarco.
Red gave interviews to both Erie paps stating,
Harry just announced to me via telegram a comeback as a Lt heavy and instructed to me to GET ME SOME FIGHTS RED!!

 

Would of been interesting may have gotten a film or 2 of him fighting but then it would have been him post prime and we may have thought of his legacy different
