I think this fight will be standing all the time until they can hit cleanly to finish the fight. I believe Tyson will KO Kimbo because we cannot compare Tyson's experience and quality of opponents with those that Kimbo has fought in the streets. However, a Kimbo's punch can also send Tyson to sleep. The disadvantage I see for Tyson is that he will not have his reflexes as he used too, but I think that he still has the advantage in this fight that should not be that long.
