Paek rose through the Toronto youth hockey system but didn't dream about becoming an NHL player until he was drafted by Oshawa of the Ontario Hockey League.
"I'm thinking, 'I might make it, I might make the ultimate goal here,'" he said. "So you push harder, you focus more, become uncomfortable more and get better every day."
He found himself in new territory when the Penguins called his name in the 1985 draft. No one in his family had ever pursued an athletic career.
"My parents thought education was important," he said. "I have an older sister who's a doctor, brother who's in pharmaceuticals, my younger sister is a lawyer. This was an opportunity to try something different and try to become a professional athlete. I convinced my parents, I convinced my family and they supported me 100 percent."
Paek played three seasons for Muskegon of the International Hockey League before he made the Penguins roster out of training camp in 1990.
"He earned it," said Phil Bourque, a Penguins radio color analyst and former teammate. "You can't think of one thing and say, 'Wow, Jimmy Paek is really good at this.' He was just so steady and a great teammate who added some value to the chemistry of our team. … He wanted to win, he wanted to succeed so badly that he became a very important piece to our puzzle."
Paek played in three regular-season games his rookie season, unable to crack a veteran defense corps that included Hockey Hall of Famers Paul Coffey and Larry Murphy.
Pittsburgh sent him to the Canada national team to get him ice time and recalled him as a "black ace," a depth and practice player, on the Stanley Cup Playoffs roster.
"I'm skating around as a 'black ace,' a ninth defenseman and (coach) Bob Johnson comes up to me and says, 'Keep smilin', Jim, keep working hard, you never know what's going to happen.'"
Johnson proved prescient. Three Penguins defensemen -- including Coffey -- were injured and Paek was thrust into action in the Patrick Division Final against the Washington Capitals.
"Johnson's words were great advice and it sure paid off," Paek said. "I played in the (Stanley Cup) Final and I got a goal. You couldn't write that story any better."
