For one thing Hagler is more highly regarded in standing on the best middleweight's list's. Why not. Hagler was more pleasing to watch. Hagler could switch up and Box from either side. To this day I've never seen a fighter who come's close to Hagler that could box from either side with equal effecti. The Hagler fight's are more remembered than the Hopkin's fight's. Hagler's best fight was Hearn's. Hopkin's was Trinidad. The question now becomes who was better. I liked Hagler better. Doe's that mean Hagler was better than Hopkin's. No, IMO. The VS. part .My thought is if they would have fought each other when they both were not champion's. They each had two defeat's. Not when they were champion's. Who win's. I don't know. Never count out Hopkin's a master outside of the ring as well as inside of the ring. That's how close it is. Hagler was one determined fighter. So was Hopkin's. Both were gym rat's. Solid as Solid can get. On and On. Out of all the myth fight's ever in time this is the one that would be on the top of my list IMO it's a tie.
