Re: Heavyweight Champions--Who would be the best in MMA?
I guess most people are going to pick Jeffries here.
I'd pick Marciano. He's mentally so attuned to the task at hand that the change wouldn't hurt him as much as the others. He never gives up and his head is hard. Plus he has real power.
The only thing would be he may not pick up any grapping skills.
But that COULD be true of any of them, even Jeffries and Johnson.
