Leafs owner Conn Smythe was so taken by the play of the teenage Harvey Jackson that he signed him to a contract and got him into a Toronto sweater as soon as possible. When Jackson made his NHL debut in 1929, he was, at 18, the youngest player in the league. Soon, he was playing with two other fresh faces, Joe Primeau and Charlie Conacher, and so was born the Kid Line. The name of the line itself is so famous that it is used to this day to describe any line of three young, talented players. In their day, the original Kid Line was spectacular. In 1931-32, his third year in the league, the left winger Jackson scored 28 goals and his 53 points was tops in the league. The Leafs also won the Stanley Cup in their first year at Maple Leaf Gardens. Jackson starred with the Leafs for a decade, averaging nearly 20 goals a year, an astronomical number for that era. The Leafs went to the Cup finals seven times in the 1930s, and the Kid Line made the Leafs the top-scoring team in the league. Jackson finished his career with two years in New York playing for the Americans and three years with Boston. He was a member of four end-of-year All-Star Teams (1932, 1934, 1935, 1937) and played in the three pre-war All-Star Games in 1934, 1937, and 1939.
