I do think the Gophers (and other teams) who have Olympic sized ice sheets have a disadvantage come tourney time compared to those who play on NHL or North American rinks.
That was the knock on St Cloud for years. They’d have a really good regular season and win most of their home games because they had players with speed who could use that extra ice to their advantage. But when the post season came around, they often lost that advantage on a smaller sheet. Doesn’t appear to be a problem this year, so far.
