Where would these top 10 heavies from 1988 according to the ring mag rank now if they were active and the same age they were in 1988? Tyson was champ Evander Holyfield Carl Williams Adilson Rodrigues Tim Witherspoon Michael Dokes Razor Ruddock Tony Tucker Orlin Norris James (Buster) Douglas Francesco Damiani
Adilson was knocked out by a low level fighter: 19th fight: Loss 18-1 Andre van den Oetelaar KO 5 17/11/1985
Rodrigues currently resides in São Paulo, São Paulo, where he is being treated for Alzheimer's disease originating from dementia pugilistica.
If Holyfield isn't dramatically changed by having to pass a urine test it would be puncher's chance only for everyone. I think he scaled up to HW better than Usyk (as far as I've seen to date).
Judging and meshing this list with who's currently in the top 10: Tyson, Evander, Tucker, Buster and Razor would be in the top 10.
