in 1970 in 1974 Nicknamed "
The Riverton Rifle" and "
The Chief", Leach was drafted third overall by the
Boston Bruins in the
1970 NHL Amateur Draft. Leach scored his first NHL goal in Boston's 6-0 home win over St. Louis on January 31, 1971. He scored nine goals during his time with the Bruins. Boston traded Leach, Rick Smith and Bob Stewart to California for
Carol Vadnais and Don O'Donoghue on February 23, 1972. After playing three seasons in Oakland, the Golden Seals traded Leach to Philadelphia for Larry Wright, Al MacAdam and 1974 first rounder (Ron Chipperfield) on May 24, 1974. He contributed to the Philadelphia Flyers' Stanley Cup win in 1974-75. Leach finished his NHL career with a one-season stop with the Detroit Red Wings. Leach's best season was the
1975–76 season with the Philadelphia Flyers, when he set career highs in goals (61), points (91), game-winning goals (11), and plus-minus with a +73 rating. Leach's 61 goals earned him the goal-scoring title for that season, as well as the current Flyers franchise record for most goals in a season. Leach is perhaps best remembered for being one of only six players, the first
Flyer, and the only non-goaltender to win the
Conn Smythe Trophy, awarded to the MVP of the
Stanley Cup playoffs, as a member of the losing team in the Final. He followed
Roger Crozier (
Detroit Red Wings, in 1966) and
Glenn Hall (
St. Louis Blues, 1968) and preceded
Ron Hextall (Philadelphia, 1987),
Jean-Sebastien Giguere (
Mighty Ducks of Anaheim, 2003), and
Connor McDavid (
Edmonton,
2024). He earned this distinction in
1976 while setting NHL records for most goals in a single post-season, with 19 in 16 games, surpassing the
Montreal Canadiens'
Newsy Lalonde's 1919 mark of 17 goals, and longest consecutive games goal-scoring streak in the playoffs at 10, bettering the seven set by another Canadien,
Maurice Richard, as his team went on to be swept in the final by Montreal. The latter record remains unrivaled, but the former was matched by the
Edmonton Oilers'
Jari Kurri in
1985, although Leach established it in two fewer games. During that same playoff season, Leach recorded a five-goal game against the
Boston Bruins, a record he shares today with
Maurice Richard,
Darryl Sittler,
Mario Lemieux and
Newsy Lalonde. Also, his total of 80 goals for the season and playoffs together set a new NHL record, which stood until
1980-81 when
Mike Bossy of the
New York Islanders scored 85. Leach played 934 career NHL games, scoring 381 goals and 285 assists for 666 points. Reggie was also part of the Flyers' 35-game unbeaten streak in 1980, which is a record that still stands today, in addition to the Flyers' home game unbeaten streak of 22 games in the same year. Leach also played for Team Canada in the 1976
Canada Cup, helping to win the championship. He was also a member of the NHL All-Star teams in 1976 and 1980. ==Coaching career==
