I don't think Taylor could beat Hagler at all, but Hearns I think he would knock out simply because he has Hearns' height and speed, but he is too strong for Hearns IMO. I think Duran as well is far too small and by the time he was a middleweight slow to beat Taylor. I don't get the SSM piece? Are you saying he wasn't at his prime? If so neither was Leonard when he fought at middlewieght, and SSM wasn't comming off 3 years retirement, but he was just an example of somebody who was fast and threw good combinations that was still not enough to beat Winky or even come close, but he is a little smaller than Leonard and thats why this fight would be closer. BTW I am not saying Leonard would lose hands down I just think Winky would get the best of him, but I could easily see the big hearted and even more talented Leonard pulling off a well earned victory.
