Michael Spinks vs Ray Mercer, 1988?

Mercer the 1988 Olympic champion against the unbeaten version of Spinks who got annihilated in 91 seconds by Tyson? I would take Michael to beat Ray by a unanimous points decision. I know Mercer was just starting out as a professional that year or the next year but I think Michael would have beaten him when Mercer was at his best as well as 41 year old Holmes outclassed Mercer and Michael beat Larry twice albeit controversially. But there was nothing controversial about Homes' victory over Mercer as Larry made Ray look like a fool at tmes lol.
