Against the likes of Ernesto Hoost, Badr Hari, Jerome Lebanner, Mark Hunt etc? Juice was legal in k-1 so also Conor would be much bigger so don't play the card "he is too small". Kaoklai was lighter than Conor and he beat Mighty MO, Alexey Ignshov and advanced to a K-1 semi-final. So it wouldn't be that crazy if he managed to win the title or at least go into a semi-final like Kaoklai did.
