And enough's enough with what I'll call "frivolous" coach challenges for alleged goalie interference. There are so few goals scored in some games that coaches seem to be thinking they might as well give it a try, because what's to lose but a timeout and the chance to challenge later. It has reached the point where just about every goal is followed by a question mark--Will it be challenged?

Last night, Pittsburgh's Mike Johnston had no reasonable chance of getting a Columbus goal wiped out, and the same was true for an appeal made by Edmonton's Todd McLellan in Detroit. Mind you, we've seen some mystifying calls that did cancel goals, so all aspects of the highly controversial issue continue to need a….pardon me….review.

The results of mine are as follows: If it's not a goal, it must be a penalty. If it's not a penalty, it must be a goal. An unsuccessful coach's challenge brings a delay of game penalty, much the same as an unsuccessful stick measurement.

Below, watch both the Pittsburgh and Edmonton challenges...
