But what did the officials do? They checked the tape! They made sure it was right! They weren't going to award a Stanley Cup Final victory to a team based on the human element.
They found out it WASN'T a goal and play resumed.
Now the Flyers won it later and made it a moot point, but just think about that for a second. Without instant replay a team could have won a Stanley Cup Final game they didn't deserve. The difference between a 2-1 hole and a 3-0 hole in a best of seven series is enormous. (Don't tell the Bruins that.)
The call was right. There is no "But the Flyers didn't REALLY win it" caveat.
