Vitali was a world champion kick boxer but was knocked out in a martial arts bout also, do you feel any heavyweight boxer could have beaten him in a crossover bout?
Jeffries, Johnson, Jeremy Williams, Danny Hodge, maybe Carnera and Berlenbach. The bigger guys who trained in wrestling or judo. I'm sure there are plenty of others.
Bob Fitzsimmons detailed record shows him participating in some wrestling bouts in 1890: http://www.cyberboxingzone.com/boxing/fitz.htm
Holmes double legs him (former st. champ wrestler) and pounds him out. Larry is the GOAT boxer who should have fought MMA.
IIRC Mark hunt survived THAT headkick at @2:03. Hardest chin I've ever seen in any sport. Vitali only threw with his lead leg, a few right high kicks could have made him great.
Good list and GREAT call on Olympic silver medalist Dan Hodge. Jefferies, I know, trained with Frank Gotch. Jack Dempsey practiced JuJitsu to stay in shape.
If Holmes was a legit wrestler then he may indeed have been a badass MMA guy. Wrestling and boxing are GOOD bases for MMA.
I'll say what you are desperate to hear. You are desperate for someone to mention Mike Tyson and AJ, aren't you? It's like @Fergy & LaMotta's old threads where they would dress up a thread in an incognito way but the objective was to get a Mike Tyson discussion going.
