Chantal Tkachuk was sitting in the stands at T-Mobile Arena and didn't hesitate when asked how much time she spent at home in St. Louis. "Actually, since the beginning of 2018, I will be out of town every weekend but one or two until the middle of April," she said, smiling. Chantal is the air traffic controller of the Tkachuk family, no small task with a husband and three children traveling around North America in pursuit of hockey excellence. Husband Keith Tkachuk, who played 19 seasons in the NHL before retiring in 2010, put it best, in an athletic context. "It's zone coverage, I'll tell you that," Keith said. On this morning, Chantal was watching oldest son Matthew, 20, take part in the Calgary Flames' morning skate. She wore a No. 19 Flames jersey (Matthew's number) thrilled to be part of the Flames moms trip, starting at the home of the Vegas Golden Knights on Feb. 21. It was a rare chance to spend one-on-one time with Matthew, who has 49 points (24 goals, 25 assists) in 64 games this season. Her middle child, Brady,18, a freshman on the Boston University hockey team, helped the United States win the bronze medal at the 2018 World Junior Championship with nine points (three goals, six assists) in seven games. Brady is the No. 3-ranked North American skater on NHL Central Scouting's midterm ratings of prospects for the 2018 NHL Draft in Dallas June 22-23.
