General manager Jeff Gorton announced the hires Tuesday. Leetch and Richards will work on prospect development and assist with on-ice development for the Rangers and their top affiliate, the American Hockey League's Hartford Wolf Pack.
These are the latest moves in an offseason that already included former captain and assistant general manager Chris Drury taking over GM duties in Hartford, and New York hiring longtime NHL head coach Lindy Ruff as an assistant on Alain Vigneault's staff.
Leetch played parts of 17 seasons with the Rangers during his Hall of Fame career and was the top defenseman on the team that broke the franchise's Stanley Cup drought in 1994. Richards played three seasons in New York from 2011 to 2014, helping the Rangers reach the 2014 Stanley Cup Final.
