I believe the coach's challenge for goaltending can only be used if goaltending is actually called and only in the first 38 minutes of a game.
In the final two minutes, officials can initiate their own review of potential goaltending on shots where goaltending wasn't called on the floor. It appears the officials did not initiate a review of this play at the end of regulation, which is insane. Or, maybe they did review and the braindead TV crew didn't inform us. That is possible. The review would have likely had many more camera angles than the two crappy ones floating around from the live TV broadcast. Although watching both angles, I think it was goaltending.
