"Here, it was my wife and I, and Connor's twin brother, Ian, watching Hockey Night in Canada.
"But Vancouver - where I'm from - was kind of a second home for Connor growing up. For him to be able to play his first game in that city, in that rink, was awesome.
"My father, my sister, all our friends that we grew up with around there - they were all watching the game, too.

Dave, who logged 126 games in the NHL, still remembers the first time he hit the ice in the big leagues. He was 21 at the time, lacing 'em up at the old Chicago Stadium as the Blackhawks hosted the Toronto Maple Leafs on a chilly, December eve - five days before the Windy City's infamous, 'heart-attack' snowstorm.
