I would not be so sure. Foreman's best "wins" in that time frame were stepping stone Cooper and the Ghost of Cooney. Old Foreman was slow of hand and foot, not in the same zip code as Douglas plus Foreman never demonstrated lateral movement combined with combos like Douglas did on that night. Foreman came back for the pay checks, Douglas on one night fought for his Mother. After Tyson's Tokyo loss Foreman fought some more Filler until he met average punching Holyfield who used him as a Heavybag., a year later Stewart turned his head into a grotesque Mellon. It is highly unlikely that Tyson would wake up in a Brothel like he did for Douglas on fight night when facing even old Foreman, he would come out to make a statement.
Foreman was, however, about to produce his performance against Holyfield, so given a title fight with Tyson, we can expect his level best. As I say it really hinges on Tyson. If he has a good camp or even just shows up hot on the night, he’ll win. But if it’s literally the guy who just freaking stood there with Douglas I think he gets steamrolled.
