Good points, but I'm thinking peak vs peak. Also Holyfield used PEDs (which ere common for his era) Quarry did not. So there lies a gray area. Holyfield's biggest advantage vs Quarry is Evander never cut like Quarry did. Ruiz clearly one 2 of the 3 Holyfield fights, regardless of ho old Holyfield was at the time. One last thing, Quarry was washed up by age 29, mainly due to the primitive training techniques, like brutal sparring sessions. Holyfield on the other hand did not spar heavily.
