I agree with you if it makes you feel better.
Still was a goal however.
It was extremely likely that the puck went in, and I believe it did. However, because of the angle there is a scenario where the puck could have still been touching the goal line while not being visible. If Niemi happened to stop it as soon as the puck went behind the post then it wouldn't have fully crossed the line. The NHL rule states that conclusive evidence, not just extremely likely evidence.
Like I've said elsewhere, the rule needs to be changed.
Why are goalies allowed to cover the puck halfway across the ****ing Atlantic?
now they're gonna shoot next time when a pass should be made and vice versa. the rangers in a nutshell.
