Re: Greatest Middleweight once and for all- Greb? Monzon? Hagler?
Greb beat middleweights in over the weight matches. People were able to distinguish between that and a true light-heavyweight contest then.
If memory serves, Jeff Smith weighed around 165 pounds for their 5/19/17 fight. But nobody considered him a "light-heavy" at that time. Just a middleweight who didn't need to meet any weight requirements.
