Fasel said the world governing body for hockey is considering moving all international competitions to smaller, NHL-sized ice surfaces. He believes the smaller ice can contribute to the fan’s excitement and emotions.
“More and more now when we are watching the games, especially the juniors here in Canada, maybe one of the reasons the tournament here is on a very high level, maybe, is the size of the small ice,” said Fasel on Saturday ahead of the medal games at the world junior hockey championship in Vancouver.
