No, they were not dominant. On ice Coris +/-: Komarov -7, Kadri -8, Grabner -2. They did have some good moments, though, obviously.
They mostly went up against Kopitar, Lucic and Gaborik, and they were largely dominated (on ice corsi % 56-62% for those Kings).
It definitely wasn't "winning the right way". But the Leafs did keep them out of the high danger scoring zones, as most of the Kings' surplus Corsi events were missed, blocked and low-probability shots. Still, a Carlyle type victory, and not what most of around here would call "winning the right way".
