"Two hotly disputed calls -- which were wrong, according to instant replays -- might have cost the Coyotes two points last week.

In another game, an apparently malfunctioning clock started late, and the Los Angeles Kings stole two points by scoring with four-tenths of a second remaining to beat the Columbus Blue Jackets.

And being that the Coyotes and Kings are in the same division and struggling to reach the top eight in the Western Conference, coach Dave Tippett's team suffered a double-whammy.

In the Coyotes' case, Martin Hanzal was called for goaltender interference that negated a goal by Ray Whitney, then an offsides against the Anaheim Ducks was not called, and they scored a few seconds later.

Nothing can be done about those, but what about moving forward?

Tippett said he has been at a couple of meetings in which the topic of a coach's challenge was discussed, and he thinks it's something to consider."
