For Chantilly Coach John Mercer, ice hockey is a family affair. He started with the Chargers as an assistant when his oldest son Justin joined the team, and then took over as head coach when his younger son Jack continued the family tradition.

But there’s one aspect of Mercer’s coaching style that could be embarrassing for any child: He wears a bright purple suit to every game.

“I”m asking these guys to go big on the ice,” Mercer said. “This is my version of going big with the kids. And they seem to get a kick out of it.”

And Chantilly has gone big in the Northern Virginia Scholastic Hockey League (NVSHL) this season. The Chargers are the first overall seed going into the playoffs, and only have one loss.

Mercer, who works in insurance, is known for his loud suits at the office, and one day some of his players noticed a holiday suit in his car that he was going to wear for a work function.

“They’re like ‘you’re not wearing that to the game on Friday, are you?’” Mercer said. But the coach quickly reassured them that he was sticking with the purple suit, which he has committed to wearing throughout the playoffs.

“It’s become sort of a superstition kind of thing,” Mercer said. “They’ve really bought into it and they get a kick out of it.”
