From the NHL's Situation Room blog, the official explanations on the final play of Game 4:
Interpretation of goalie interference rule: New Jersey at Carolina - 19:59 of the third period
04.21.2009 / 10:34 PM ET
The NHL's goalie interference rule sets a mandate to protect the goalie in the blue ice – to let the goalie do his job. In the white ice, it is a more delicate matter, including who moved into whom. The referee has one split-second look at it and it is a judgment call. NHL Hockey Operations has no video review capacity in this instance. Hockey Operations officials agreed with the call on the ice, that it looked like the goalie, Martin Brodeur, moved out toward the skater.Video Review: New Jersey at Carolina - 19:59 of the third period

Crosses the line
Wed, 04/22/2009 - 08:36 — rocheccwIn basketball it is when the ball leaves the player's hand, but in hockey it has always been that the entire puck must cross the goal line before time expires.
Cross the line

Video
Wed, 04/22/2009 - 08:47 — rocheccwYou're welcome. I went home & watched the video highlights over & over again. They showed a still shot of the puck crossing the line at the .2 second mark. It was unbelievable. It was the main highlight on verses, and they all agreed that it was a good goal with no goalie interference.
From my seat in the stands I knew it was in but I couldn't tell if it beat the clock. The goal light never went on because it locks out the button when time expires.
Hopefully, this will be the spark the Canes need to finish this series.
Canes in 6!
When it crosses or when it's shot?
Wed, 04/22/2009 - 07:10 — CaniacGuyAs I read that release, it appears that the validity of a goal is based on when the puck crosses the line. I always thought it was when the shot was taken ... when did the puck leave the stick. Have I been wrong all these years ... seriously?
Yep
Wed, 04/22/2009 - 09:01 — ldecock (author)In basketball, it's when the ball leaves a player's hand. In hockey, the puck has to completely cross the goal line before time expires.
The last buzzer-beater I remember was Kevyn Adams in Atlanta in March 2004.
And to think

Thu, 04/23/2009 - 09:11 — esteban1949you are so right. Kids learn some of the "darndest" things from parents and grand parents...all they do is to be like owls and sponges...they sit there...watch,listen, and soak it all up! Then many folks wonder why their kids don't do well in school or get sent hope for disrespecting the teacher and sadly it goes on and on...to other areas of life...and even at home, where we read the news about how some kid slaps his/her mom, and etc...yep, gots to watch out for them little eyes & ears.
have a good day sir..
Go Canes !!
Boo Hoo.......
Wed, 04/22/2009 - 05:45 — CanenutCanes needs to go into Thursday and get infront of him early. He is furstrated and they need to keep up the pressure. We saw what happens to him last year during the NY series. He may be the all time winningest goalie but last night he was a big cry baby. What kind of example was setting for all the young goalies out there that want to be like him. I have seen Cam get frustrated and slam his stick but never going over and argue with the ref. Thought only "A" and "C" were allowed to talk with the refs? Boo Hooo..... Cry all the way back to Jersey.
