8. Junior Dos Santos
‘Cigano’ is definitely past his prime now, but in terms of MMA boxing, he’s one of the best. The Brazilian is very light on his feet for a heavyweight and puts combinations together very well. He famously defeated Cain Velasquez in under one round. More than half of his strikes were punches.
Now his chin is starting to let him down, but Dos Santos is still technically excellent. Before losing to Francis Ngannou he was planning to recapture the heavyweight belt and then challenge Deontay Wilder. That’s probably not such a good idea now, but maybe 10 years ago it would have been a sight to see.
