The players weren't the only ones building legacies Sunday night.

Mike Sullivan became the first American-born head coach in NHL history to win the Stanley Cup more than once when his Pittsburgh Penguins clinched their second straight championship with a Game 6 victory over the Nashville Predators.

The 2017 Stanley Cup Final featured two American-born head coaches for the first time ever, and Predators bench boss Peter Laviolette became only the fourth NHL head coach in history to take three different teams to the championship round.

Sullivan, who hails from Marshfield, Mass., was hired by the Penguins to replace the fired Mike Johnston in December 2015.
