"Just having some fun. always a good way to end off,'' explained Ward. "They don't even know they're working hard but they're getting some work in. Working with their feet, which is important in hockey, too.
"This is the way it works - ball's in the air, you play handball. But you can only hold onto the ball for three seconds before you have to pass it.
"As soon as the ball hits the ice you're playing soccer. And the goalies can't hold onto the ball. They gotta play out."

"A lot of fun. I can't really remember the last time I saw a soccer ball on the ice. Something different. Saw a lot of smiles out there."
