4. Referees must call the same game from the opening faceoff right
through until the end of overtime. It's horrendous to see some of the
crap that goes on at the end of the third period when the players know
that the refs have "put the whistle away".  Maybe the refs  don't want
their call to "affect the outcome of the game".  Bad officiating leads
to undeserved goals (or the lack of deserved goals).  And the last time
I looked,  a goal in the opening minute counted just as much as one in
the last seconds of the third.

I think that is the way hockey should be called. This swallowing the whistle in 
the third period is stupid.
