FLoyd would KTFO Kirkland. But, until that point it would be all action. Floyd would never fight him though, cause Kirkland has power, and Floyd don't mess with dat sh!t.
I think Void would outsmart Kirkland. Void would take Kirkland several rounds and knock him out with his skills...............Ishida knocked Ward out in the very first round..........
Kirkland would not destroy Molina under any circumstances. Molina has an awkward style that makes him hard to hit clean and is very tough. But I do agree he'd be a better matchup than Khan, if only for the reason that Kirkland would make Floyd work every second he was in there. And it does offer some slight intrigue in that Kirkland has a terrible chin, so I suspect Floyd stops him, but if Floyd doesn't have the power to get Kirkland's respect, he might be in trouble vs Kirkland's nonstop workrate. That said, like Khan, Kirkland doesn't deserve the fight and Floyd wouldn't go for it anyway in his case. Too much risk.
