Mike Sullivan wouldn’t say who is going to play for Team USA in Thursday’s final of the NHL 4 Nations Face-Off in Boston. But everybody on his roster except for Bruins defenseman Charlie McAvoy is capable of playing when the Americans face Canada at 8 p.m. at TD Garden.

McAvoy is married to Sullivan’s daughter Kiley, who recently gave birth to the couple’s first child. McAvoy plays defense for the Boston Bruins, Sullivan coaches the Pittsburgh Penguins and their careers had not overlapped until now, when they’re on the same team with the United States at the 4 Nations Face-Off.
