Vitali Klitschko vs. Jess Willard under old rules.

Vitali under any rules.

 

Agreed. Jess doesn't even have a puncher's chance in this one, and unless he scores a fluke/bogus knockdown, sorta like Wepner-Ali or Roldan-Hagler, he's losing every minute of every round until he's KO'd or quits.

 

I'll say Klitschko by KO ( rounds 8- 10)
But if vitali goes back in time his training, conditioning and technique would all change, and the fight could be perhaps closer.
But I can't pick Jess over Klitschko.

 

Vitali was a martial artist (kickboxing/karate/boxing) from his preteen years, while living in a concrete one bedroom apartment. He was hardly a pampered amateur baby. This would be a heavy bag session. All depends on how much a stomach the ref or Jess' corner had for the brutality.

Vitali is just better.

 

Vitali, every year, every set of rules.
