I'd also agree that based on the replays shown on TV, and the fact that Shegos did not see it cross the line, that there was no way it was a goal.
However, from one close up replay, you can see the puck in the webbing as Mannino catches it outside the net, then a later replay clearly shows the top half of this glove behind the pipe. I have NO doubt that the puck was across the line, but can't disagree with the call as made.
Mannino would not say if he thought it was over or not in a post game interview, he chose to say only that he believed the right call was made. I think he knows full well (as does Fabian) that they puck was across the line, inside the glove. I'd guess Carle knows as well.
Also, from the pic, it appears Shegos has an excellent view of the glove in relationship to the pipe, although he may not have known what part of the glove the puck was in.
Did the replay official see only what we saw on the TV replay? I find it hard to believe there was not an overhead cam for the official, since review was required for every goal scored in th NCAA's. Were they really dependent on the ESPN cameras only?
