The last time a high profile boxer entered the octagon with no MMA experience it was James Toney at UFC 118. Former UFC heavyweight/light heavyweight champion Randy Couture easily took Toney to the ground and Toney never got up, his huge lack of experience in ground game exposed.
Heavweight boxer Ray Mercer had a first round KO against Tim Silva in the octagon and was choked out in the first by the late Kimbo Slice, a street fighter and relative newcomer to the MMA game at the time.
If Floyd does step in the octagon, he will obviously be the most skilled boxer ever to do so, albeit at a tremendous disadvantage outside of striking.
