3. Tim Horton

Tim Horton played his first 20 Seasons in the NHL with the Toronto Maple Leafs, where his physical strength and toughness set him apart from the other Defenseman.

Horton debuted in 1950 and was a Second Team All-Star in 1952-53.  He could drop the gloves and intimidate when needed, though he was not a player who drew penalties, often considering his physical style of play.  Horton had a phenomenal decade in the 1960s, where he anchored Toronto to four Stanley Cups, was a First Team All-Star twice, and a Second Team All-Star three times.  Horton finished in the top-four in Norris voting six times and was the runner-up twice. 

In 13 different years in Toronto, Horton was in the top ten in Defensive Point Shares, and he led the league in that advanced metric twice (1953-54 & 1962-63).  As of this writing, he is seventh all-time in DPS.

Horton was traded to the New York Rangers in 1970, and he later played for Pittsburgh and Buffalo, where his career ended following his death from a car accident.  He was elected to the Hockey Hall of Fame in 1977, with the Leafs honoring him in 1995.  His number #7, which he had sometime after fellow honoree, King Clancy was officially retired in 2016
