A couple of posters over at MGoBoard provided screen caps for all. This clearly shows it. The puck's in the net. Game over. They got it right.
Thank you Cowbellguy and Skone82.
I'm sorry the Frozen Four won't include 5 WCHA teams this year, but Michigan won and it was the correct call. The puck is actually moving toward the goal line in this photo, so even if all the white space between the black blob and black line doesn't convince you, there's absolutely no question that the puck was in the net.
I love the internet.
