A member of the Boston Bruins for his entire 13-year career in the NHL, Jack Crawford was known for his hardnosed play and hence why the Bruins never seriously considered dealing him.  Early in his playing days he would help the Bruins win Stanley Cups in both 1939 and 1941 and in the first Cup winning year he was the National Hockey League leader in Defensive Point Shares.  Later, Crawford would be named a Second Team All-Star (1943) and First Team All-Star (1946).  He retired with 178 Points over 548 Games, a good number for a Defenseman in those days. 

While Ted Harris was not a goal scorer by any means (he never had a 10 Goal Season) he provided rugged defense and a physical presence over his career.  Five times an All Star, Harris would win five Stanley Cups over his career (four with Montreal and one with Philadelphia) and he was a named to the Second Team All Star roster in the 1968-69 season.  Notably in the 1965-66 season (a campaign where he recorded no Goals) he would lead the NHL in Plus/Minus.

Bob Murray played his entire NHL career with the Chicago Blackhawks where he was named a two-time All-Star.  Murray was never ever considered among the upper echelon of NHL Defenceman but this was a hockey player who was in the league for 1,008 Games and it was all with one team, a testament to his value to a franchise.  Murray scored 514 Points over his professional career.

A member of the Montreal Canadiens 1916 Stanley Cup Championship team when it was won when they were in the National Hockey Association, Bert Corbeau would have a few distinct firsts in the NHL.  Corbeau was the first player to play for both the Canadiens and the Toronto Maple Leafs, the first season leader in Defensive Point Shares and the first player to have 100 Penalty Minutes in a season.  Corbeau would have three seasons with 10 Goals, which is an excellent metric for a blueliner in that era.
