Not to be missed, NHL director of officiating Stephen Walkom goes over the points of emphasis for referees and linesmen this season.

Just a warning: They show Kurtis Foster getting his leg broken trying to touch up an icing early in the video. If you didn't know what happened, it doesn't look that bad. But since we all know what happened, it's pretty cringeworthy.

Also, the league makes clear any contact with the goalie -- deliberate, incidental, even some that could be interpreted as unavoidable -- will result in a disallowed goal. I disagree with the liberal interpretation of goaltender interference because I think defensemen will just start nudging forwards toward the crease hoping for a call, although I do commend the league for trying to protect goalies from crease-crashing.

Tim Gleason makes a cameo appearance with a gentle tug on Vincent Lecavalier's elbow on a breakaway that Walkom points out is still a hooking penalty.
