He got completely outclassed and knocked out. Styles make fights. Everyone Robert has fought at Middleweight has been a short wrestler with a overhand right. He hasn't fought anyone at 185 with higher level boxing than him. High level strikers have always been his weakness. IMO, KG is a better version of him. Just like Conor's toughest fight was Mendez for the Interim, then the actual fight was easy work, we might be seeing that again.
