3. He retires
If Fleury chooses to retire then the team gets back that cap space they were going to use on Fleury. They could use that cap to help a team that is hurting and potentially add some assets from a team the way they did it with Tampa Bay. However more likely would be they try and add another free agent or two.
The free-agent market on goalies is starting to thin with Tuukka Rask, Jonathan Bernier, and Cory Schneider being three of the biggest names available. Although they could decide to try and offer a contract to an RFA goaltender in Igor Shesterkin from New York or Juuse Saros from Nashville. =
The Blackhawks are in a tough position should Fleury choose to just walk away from the NHL. The team would need to know sooner rather than later before more and more rosters get set and teams start taking more free agent goalies that are available.
"Best Blackhawks Goalie of All-Time: Esposito, Hall, or Crawford?"
Hopefully, the Blackhawks will share more soon about the status of Fleury and the team. Obviously, the entire fanbase would be ecstatic should Fleury decide to play in Chicago for the season. Having a goalie like him would definitely help push the franchise towards the playoffs.
