Hearns might not be much smaller, but Walker hurt heavyweights and took their punches. He was perhaps better than any other fighter in history at overcoming a height and reach advantage.
Given the problems that Hearns had with more durable punchers at middleweight, I don't quite see the rationale for making him favourite here.
Still not convinced?
What about some of the other great middleweights on Greb's resume?
You have George Chip, Mike O'Dowd, Jack Dillon, Mike Gibbons, Eddie McGoorty, Jeff Smith and Tiger Flowers.
Yeah he got sparked by Hagler and Barkley but that isn't overly comparable here when we consider fight night weights.
I make hearns favourite because he's one of the most gifted fighters in boxing history and it takes something even more special than walker for me to make him an underdog.
hearns is inside my top 10 h2h list all time. Seemingly I rate him higher than you do, which is fine because it is a subjective sport.
Just a shame we'll never get to see this fight happen.
