Detroit used 14 defensemen last season. Two (Filip Hronek, 65; Patrik Nemeth, 64) played more than 53 of its 71 games.
"We're looking to fill spots on the left and right side to be honest," Yzerman said. "There's a huge hole on our [defense]. We won't be bringing back Jonathan Ericsson. We won't be bringing back Trevor Daley. (Each will be a free agent). So there's two spots on our left side that need to be filled, and we have Patrik Nemeth, Danny DeKeyser (eight games last season, back injury), and Marc Staal fits in nicely on the left side. He's a good, solid defender, good size (6-foot-4, 209 pounds). Obviously he's been in the League a long time. He's a good penalty killer. So he plugs a hole for us on the back end."
Staal scored one goal when New York was swept by the Carolina Hurricanes in the best-of-5 Stanley Cup Qualifiers this postseason.
"The success we had throughout Marc's tenure, including a trip to the Stanley Cup Final (in 2014), would not have been possible without his tireless efforts on and off the ice," Rangers general manager Jeff Gorton said. "The respect we have for Marc is immeasurable, and we wish him and his family all the best."
With Staal, the Rangers advanced to the Eastern Conference Final three times in a four-season span (2012, 2014, 2015), losing to the Los Angeles Kings in five games in the 2014 Cup Final, and won 10 Stanley Cup Playoff series. He scored 20 points (seven goals, 13 assists) in 107 postseason games and is one of three Rangers to play at least 100 postseason games (Henrik Lundqvist, 130; Dan Girardi, 122).
Staal played 18,394:47 with the Rangers, the most by any skater since the NHL began to track ice time in 1997-98. He was an alternate captain for 10 seasons (2010-20), one of three Rangers to either be captain or an alternate captain for at least 10 seasons (Brian Leetch, 13 seasons; Mark Messier, 10 seasons).
His brother, forward Eric Staal, was traded to the Buffalo Sabres by the Minnesota Wild on Sept. 16 for forward Marcus Johansson.
