When news broke that Marian Hossa would miss the 2017-18 season with a progressive skin disorder, it shocked both Blackhawks fans and the entire hockey community.
His future after that is unclear, and if it's the end of what is surely to be a Hall of Fame career, Hossa will go down as one of the best two-way players in league history and a class act both on and off the ice.
He's also been a crucial part of the Blackhawks winning three Stanley Cups, and there's a case to be made they don't win the first one in 2010 without him.
In a playoff-defining moment with Chicago, Hossa capped a two-goal comeback win in Game 5 against the Nashville Predators of the first round of the playoffs by racing out of the box after serving a four-minute penalty and scoring in overtime to give the Blackhawks a 5-4 win and 3-2 series lead. The Blackhawks went on to win Game 6, and eventually snapped a 49-year championship drought.
