Orr just seems smarter out there. Before he was an idiot and he seems to have finally been able to turn his game around and became a respectable roster player. Jumping Kaleta or jumping Scott is pointless. They turtle, you get a five minute major and they make you pay. He seems to be timing his fights a lot better, actually playing a decent grinders game and cutting down on the bad/stupid penalties.
Basically he's fighting only when it's good for the team, and while he's not fighting he's contributing with a physical game.
