O'Malley is about to run head first into the old "you don't know what you don't know until you know" scenario. Yan is a big step up in degree of difficulty and teeing off on unranked fighters isn't the same as fighting top contenders. He will have a height/reach advantage, but I'm confident that Yan can close that distance without too much trouble and damage O'Malley. I think a few leg kicks, some clinch work with close range boxing and then a GnP finale after O'Malley gets knocked down or tripped.
