I'm not so sure about Hearns beating RJJ.

If you are talking p4p, then maybe, but if you are talking in actual terms, then I don't think so.

Even though Hearns is taller, RJJ is physically bigger & stronger.

RJJ is probably even quicker than Hearns & I think he would be too strong for Tommy.

As said previously, Tommy didn't have the best success against elite fighters (Duran excepted & he was past it) & RJJ was an elite fighter.

I take Roy to KO Tommy in about 8.
