He scored 17 goals, tied for first among NHL defensemen with Ivan Provorov of the Philadelphia Flyers and Dougie Hamilton of the Calgary Flames. Hedman's 63 points (17 goals, 46 assists) made him the first defenseman in Lightning history to top 60 points in multiple seasons. He had 72 points (16 goals, 56 assists) in 2016-17.
Subban, 29, helped the Predators lead the League in goals (56) and points (206) by defensemen. His 16 goals were an NHL career high, and his 59 points were one shy of his personal best, set with the Montreal Canadiens in 2014-15.
