O’Brien, 31, is an interesting case, as the Ducks drafted him with the 250th pick of the 2003 NHL Draft. O’Brien only ended up playing 62 games for the Ducks in 2006-07, beginning a journeyman career that included nine games with the Florida Panthers in 2014-15.
His career stats should tell the story of his role with the Ducks, when he’d manage to play beyond the AHL level: 92 points and 916 PIM in 537 career NHL games.
Wagner, 24, was the 122nd pick of the 2010 NHL Draft. He played in nine games with the Ducks in 2014-15, but failed to score a point. He’d likely provide injury insurance.
Sgarbossa, 22, has appeared in nine NHL games, with three of those contests coming with Colorado in 2014-15.
