For teams looking to add a defenseman before the 2018 NHL Trade Deadline on Feb. 26, Mike Green of the Detroit Red Wings has earned top consideration. Green is drawing comparisons to Kevin Shattenkirk, the headliner of the 2017 NHL Trade Deadline class. Shattenkirk was acquired from the St. Louis Blues by the Washington Capitals on Feb. 27, 2017. Each is a scoring-focused defenseman, primarily used in the offensive zone and on the power play while other pairings kill penalties and handle top opponents. Like Green, Shattenkirk is a right-handed shot, and was on the final year of his contract at the time of the trade. With the Capitals, Shattenkirk had two goals and 12 assists for 14 points in 19 regular-season games. In the 2017 Stanley Cup Playoffs, he had a goal and five assists for six points in 13 games when the Capitals were eliminated in the Eastern Conference Second Round. The comparison between the two isn't perfect. Green is 32 and Shattenkirk was 28, Shattenkirk's scoring rate is higher on the power play, and Green has been shifted into a different role during the past two seasons.
