Clearly the two players have a developed a dislike for one another over the years. In last night game, Kane really did not do anything wrong. He was crashing the net looking for a lose puck. He never actually came into contact with Binnington. Perhaps the two had words during the game before this that caused Binnington to punch Kane. Or Binnington recalled Kane's dirty play from previous seasons and decided that it was time to return the favor.
