WASHINGTON — Washington Capitals right winger Carl Hagelin is a two-time Stanley Cup champion and has appeared in more playoff games than any other N.H.L. player since his postseason debut seven years ago.

It’s a whopping 125 games — the same number as his teammate Alex Ovechkin, who entered the league six years before him.

Yet this season, Hagelin, 30, has taken on an unusual label: journeyman.

With his type of accomplishments, who would have expected Hagelin to be on three teams in one season?

Hagelin went through a season of extremes over four months as he shuttled from the Pittsburgh Penguins to the Western Conference’s last-place Los Angeles Kings before being dealt to the defending Stanley Cup champion Capitals.
