I love hockey but I despair at the stunning incompetence and neanderthal thinking of the NHL when it comes to establishing and enforcing rules to promote skill and protect players (insofar as possible in a
contact sport).  The league seems content to spend minutes reviewing offsides - calling off goals due to
a toe that slid over the line by fractions of an inch, but repeated slashes and cross-checks are ignored to "let the players play". The injury to Crosby was a direct consequence of this attitude (tho' Crosby is hardly an innocent himself).
