I don't follow the Western Conference all that much, but I did happen to see the Kings live this year. My one observation at that time was that they were huge. To a man they seemed like giants and were a tremendously phsyical team.
I thought the same thing last night - they seemed to hulk over the Devils - Doc pointed the same thing out. The Devils did well to go toe to toe with them - especially later in the game, but I can't help but wonder if that will take a toll by the end of the series.
