Here are NHL players complaining about ice conditions, excerpted from article on Yahoo Sports. They were complaining about conditions on DEC 31, 2015 during practice skates, the SAME DAY as the Women's NHL Classic. Now I'm no lawyer, but seems like something was up with the ice on the day the women played:
But the above-freezing temps and the glaring sun produced an ice surface that both the Bruins and Montreal Canadiens labeled as “soft.” Boston defenseman Dennis Seidenberg said one corner of the rink that was exposed to the sun was, frankly, “dangerous.” “The one end was very slushy. The one corner was very dangerous, [when you were] kind of turning,” he said. “But what are you going to do? You have to deal with it.”
Bruins defenseman Zdeno Chara saw the same conditions. "For the most part, during practice, we stayed away from that corner of the ice, for safety reasons,” he said.
The ice conditions in that corner worsened as practice continued. “At the end, it was tough to turn. Very soft. Very slushy. It’ll be an adventure every time you go in there,” said Seidenberg.
The Canadiens also experienced some questionable ice conditions. “Not as good as an indoor rink, obviously. Very soft, very soft. And slushy at the end,” said forward Lars Eller. “Two of the corners were particularly soft.”
