Some context: Conacher was born in Toronto, Ontario on May 24, 1900. His middle name was given after the South African city of Pretoria, where British troops were fighting the Boer War at the time of his birth. He was the eldest son of Benjamin and Elizabeth Conacher, and the third of ten children overall. He had four brothers and five sisters.
Rugby football was the first sport Conacher played, and it was his favourite. He first played organized football at the age of 12 as a middle wing with the Capitals in the Toronto Rugby Football League. He played four seasons with the team between 1912 and 1915, during which the Capitals won the city championship each year. He won the Ontario championship as a junior with the Toronto Central YMCA in 1918, and in 1919 moved up to the intermediate level. With the intermediate Capitals, he was moved into an offensive role as a halfback. He excelled in the role, and his team reached Ontario Rugby Football Union (ORFU) final. In that final, the Capitals' opponents from Sarnia made stopping Conacher their priority, a strategy that proved the difference as Sarnia won the championship. Conacher moved to the senior level in 1920 with the Toronto Rugby Club where his team again won the ORFU championship, but lost the eastern semifinal to the Toronto Argonauts of the Interprovincial Rugby Football Union (IRFU). His play impressed the Argonauts, who signed him for the 1921 season. In his first game with the Argonauts, he scored 23 of the team's 27 points, and led the IRFU in scoring, accounting for 14 touchdowns and 90 of his team's 167 points as they went undefeated in six games. The Argonauts won the eastern championship, and faced the Edmonton Eskimos (renamed Edmonton 'Elks' in 1922) in the first east-west Grey Cup championship in Canadian history. Conacher rushed for 211 yards and scored 15 points in Toronto's 23-0 victory to claim the national title. Named captain in 1922, Conacher led the Argonauts to another undefeated season in IRFU play, finishing with five wins and one tie, as he rushed for about 950 yards. The Argonauts reached the Eastern final, but lost to Queen's University, 12-11. In that game, Conacher was the entire Argonaut offense rushing 35 times for 227 yards but Pep Leadley's 21 yard field goal towards the end of the game gave Queens' its victory.

Some context: David Mark Winfield (born October 3, 1951) is an American former Major League Baseball (MLB) right fielder. He is currently special assistant to the executive director of the Major League Baseball Players Association. Over his 22-year career, he played for six teams: the San Diego Padres, New York Yankees, California Angels, Toronto Blue Jays, Minnesota Twins, and Cleveland Indians. He had the winning hit in the 1992 World Series with the Blue Jays over the Atlanta Braves.
Winfield was born the same day Bobby Thomson hit his pennant-winning home run for the New York Giants, known as "the shot heard 'round the world". He grew up in St. Paul, Minnesota. His parents divorced when he was three years old, leaving him and his older brother Stephen to be raised by their mother, Arline, and a large extended family of aunts, uncles, grandparents and cousins. The Winfield brothers honed their athletic skills in St. Paul's Oxford playground, where coach Bill Peterson was one of the first to take the young Winfield under his wing. Winfield did not become a formidable 6'6" athlete until his senior year of high school. He earned a full baseball scholarship to the University of Minnesota in 1969, where he starred in baseball and basketball for the Golden Gophers. His college baseball coach was former MLB player Dick Siebert. His basketball coach was Bill Musselman, who was later a head coach in the American Basketball Association and National Basketball Association and who later referred to Winfield as the best rebounder he ever coached. Winfield's 1972 Minnesota team won a Big Ten basketball championship, the school's first in 53 years. During the 1972 season, he also was involved in a brawl when Minnesota played Ohio State. Winfield also played for the Alaska Goldpanners for two seasons (1971-72) and was the MVP in 1972. In 1973, he was named All-American and voted MVP of the College World Series--as a pitcher. Following college, Winfield was drafted by four teams in three different sports. The San Diego Padres selected him as a pitcher with the fourth overall pick in the MLB draft and both the Atlanta Hawks (NBA) and the Utah Stars (ABA) drafted him. Though he never played college football, the Minnesota Vikings selected Winfield in the 17th round of the NFL draft. He is one of six players ever to be drafted by three professional sports (the others being George Carter, Jo Jo White, Noel Jenke, Mickey McCarty and Dave Logan) and one of three athletes along with Carter and McCarty to be drafted by four leagues.
