Ron Ellis played 1,034 Games in the National Hockey League, all of which were in the blue and white of the Toronto Maple Leafs.

Ellis played in one game in the 1963-64 Season and was then a fixture at Right Wing for years to come.  Aiding the Maple Leafs in securing the 1967 Stanley Cup, Ellis had at least 42 Points each year from 1965-66 to 1974-75, with the last year seeing Ellis score a career-high 61 Points.  Ellis abruptly retired after that year, allegedly upset that he was passed over for the captaincy for Darryl Sittler.  That lasted two seasons before he returned for three more years, retiring after the 1980-81 Season with 640 career Points.

Jimmy Thomson was an underappreciated cog in the machine that won four Stanley Cups in five seasons (1947-51), which coincidentally is also not as respected as their four titles in the 1960s.

Playing at Defense, Thomson was twice a Second Team All-Star and led the NHL in Defensive Point Shares three times.  Thomson was not a scorer but was an expert passer who managed to land in the top ten in Assists twice.  Thomson played twelve years with the Leafs, with a final one in Chicago.

As a Maple Leaf, Thomson had 233 Points and ensured a lot more did not happen on his end of the ice.

If this list were based purely on popularity, Wendel Clark would be near the top.

Clark was taken number one in the 1985 Draft, and he joined a struggling Maple Leafs team that lacked an identity.  The Left Wing immediately became a fan favorite for his no-nonsense play, willingness to fight, and ability to score.  As a rookie, Clark scored 45 Points and finished second in Calder voting to Gary Suter.  The Left Wing had 60 Points as a sophomore, but in his third year, he began to be plagued with back problems that affected him for the rest of his career and resulted in many games lost.

Despite his medical setbacks, Clark remained the heart of the team and became the team captain.  A trade from Calgary brought Doug Gilmour to the Leafs and with other pieces in tow, the Maple Leafs made a deep run in the 1993 Playoffs.  Clark had his best year the season after, with a career-high 76 Points, but the Leafs dealt Clark to Quebec for Mats Sundin, and the Leaf Nation wept for days.

Clark returned two years later, where he was again oft-injured but always popular and pugilistic.  He signed with the Tampa Bay Lightning in 1998 but made one more stop in Toronto to finish his career.  

Of the 564 career Points Clark scored, 441 came in a Maple Leafs uniform.  Toronto would hang his banner in 2008, with his number 17 retired in 2016.

Hap Day entered the NHL with Toronto as a rookie in 1924, where he played at Left Wing, leading the NHL in Assists (17).  He would move to Defense afterward, playing competent two-way hockey before becoming a pure lockdown Defenseman in his fourth NHL season.

Day was very good in this role and became a team leader, earning the captaincy in 1926.  He would later be paired with the legendary King Clancy, and the two would anchor the Maple Leafs to a Stanley Cup win in 1932.  He played for Toronto until his contract was sold to the New York Americans in 1937.

Day returned to Toronto as a Coach, winning five Stanley Cups, and would capture one more as an Assistant General Manager.

The Hockey Hall of Fame inducted Day in 1961, and in 2006, his name was added to the honored greats at Air Canada Center.  His number 4 (along with Red Kelly) was retired in 2016.
