Tiger ate guys like Roldan for breakfast. Roldan would put up a spirted effort, but would get grinded down and stopped on acumulation in about 8 rounds.
Dick probably late rounds knockout. Roldan was a great top fighter and today he would be champ, but put him in the ring vs. the top greats of the past and he does lose. There were times in boxing history like now where I think he would win a title and have a few title defenses.
