I like the lower weight classes Bennie Briscoe in his prime vs the prime Roldan that challenged Hagler
Roldan was not just a strongman with a hammer like overhand right hand. He had good footwork and upper body movement and threw punches from awkward angles. The key to beating Roldan was a hard accurate jab supported by a wicked body attack to take advantage of Roldan not having the best chin or stamina. Bad Bennie had the skills to do this. Bennie on pts.
Roldan is hard to figure. I would have liked to have seen him fight more guys. he fought the cream of the crop Hagler,Hearns and Nunn, guys who were so good that they won. How would Roldan have done against lesser guys like Dewitt or Barkley ? He beat up Kinchen and Fletcher. I think he might have been champ against other guys .
