Tyson would kill Kimbo if it where a straight up boxing match. Kimbo is an internet sensation and thats about it. Look at the records of the individuals he has fought in MMA. They have a large percentage of their fights being decided by knockout, their being knocked outed. And all of them have losing records.
Let's throw all of what you said out... (just for shits and giggles).
Mike Tyson was the undisputed HW champ of the World. I don't care if he fought cans or not, he fought the best the WORLD had at the time. He also fought some of the best at the time wether he lost or not. Lewis, Holyfield.. etc.....
Kimbo would have been crushed by any of the guys tyson fought and lost to. Holyfield and Lewis both would have destroyed Kimbo in 2 rounds... Plus Kimbo is some grinder off the streets with little professional training. Tyson had the best working for him for quite some time.. I think Kimbo would still need to train for a good 10 years before he could even say he was on tyson's level..
I would love to see this fight, either way it would be a KO but I don't see how people would think that even Kimbo now would knock out a Tyson of this day and age.....
