The league is quickly trying to get a rule implemented barring blindsided hits to the head before the end of the season and in time for the playoffs.  Its a good step but I'm wondering if its timing is because (a) the league hopefully realizes its players are assets and need to be protected in order to ply their trade (b) they realized their massive blunder in the Cooke non-consequence which may have unintentionally identified this type of bush-league manouver as acceptable and within the rules and potentially attaching bullseyes to the heads of the NHL's "marquee" players  (c) miraculously discovered the existing rule regarding that type of contact needs a huge over-haul (d) underestimated the whopping backlash and public image drubbing the league and its brass have taken especially if they're trying to draw new fans to the sport.
