1982: The Washington Capitals, who have yet to qualify for the Stanley Cup Playoffs since entering the NHL in 1974, make a franchise-transforming trade with the Montreal Canadiens. The Capitals acquire defensemen Rod Langway and Brian Engblom , as well as forwards Doug Jarvis and Craig Laughlin , from the Canadiens for forward Ryan Walter and defenseman Rick Green .

The most important acquisition for the Capitals is Langway, a part of the Canadiens' 1979 Stanley Cup-winning team behind their "Big Three" of Serge Savard, Larry Robinson and Guy Lapointe on defense. Langway wins the Norris Trophy as the League's best defenseman in each of his first two seasons with the Capitals. Washington begins a streak of 14 consecutive playoff appearances in 1983.

Langway is inducted into the Hockey Hall of Fame in 2002.

On the same day, Washington coach Bryan Murray names younger brother Terry as his assistant. The Murrays are the first brother combination in NHL history to coach the same team at the same time.
