I think any great light heavyweight with power would beat Roy.
What allowed Roy to get away with all that **** what his Power. Fighter respected his Power.
I'll admit i only seen a couple of Spinks fight, 1 at light heavyweight and other best of fights. And from what i seen Spinks likes to charge forward on his opponet with great pressure and he had great power.
Roy likes to allow fighters corner him or take him to the ropes. But against a puncher and pressure fighter like Spinks that equarls danger zone.
I got Spinks winning this one. I think at this weight Roy doesn't have the power advantage against big light heavyweights like Spinks.
