No where. I'm not being contumelious, btw, I mean that literally. My HW rankings only go as far as 25 & a 1-fight Rademacher isn't troubling those rankings, regardless of who he fought and what the outcome was.
The problem with that scenario is that at some point Rademacher would have had to give ex champion Floyd Patterson a rematch, maybe sometime in 1957 or 1958. Ingemar Johansson and Sonny Liston were looming on the horizon for Pete, it would have been disastrous for Rademacher, Ingo would have kayoed Pete and so would have Liston.
We have a arguement over the undefeated Marciano vs the undefeated Rademacher. 49-0 vs 1-0. To Rademacher's credit, he retire with a 100 percent knockout rate, higher than the likes of Marciano, Dempsey,Foreman, Tyson ete.
