Not his striking, but his clinch work and pushing Graham up against the cage to get takedowns should do it.
o1.5 is also a fairly safe way to go, Kongo is good at surviving and has only been put out by Nelson & Hunt and you'd be hardpressed to find two people that punches harder then those two, Graham is more of a technical striker then he is a one-punch type of guy.
Only worry is if Kongo get's it down and starts working his GNP
