Hagelin was well-traveled this past season, beginning the 2018-2019 campaign with the Pittsburgh Penguins before getting dealt tot he Los Angeles Kings in November. That deal saw Tanner Pearson go the other way after the Kings' rough start, and just three months later he was on the move again. In 20 regular season games with the Capitals he recorded 11 points, and also added one assist in seven Stanley Cup Playoff games.
His time with the Penguins was well-spent as he went on to win two Stanley Cups with them. Now that he is teaming up with Alex Ovechkin, he is hoping for more, as are the Capitals, who gave up a third and sixth round draft pick to get him. Hagelin began his career with the New York Rangers, reaching double digits in goals in each of his first five seasons, but has only done it once since. That could be due to him never finding a consistent home, which he has now, and could very well change a lot.
