These days it's not uncommon for teams to pull their goalie down by three in the regular season.
You didn't see it ten years ago, sure. But it happens quite often now.
In the TOR/CAR game on Saturday, the Hurricanes were down by three and pulled their goalie with about 6:00 minutes left. They scored and then put the goalie back in and scored another, making for an anxious finish for Toronto fans.
I remember a game between TOR and BOS from earlier in the season where the Bruins were trailing 3-0 and pulled their goalie and TOR scored another immediately.
