Which Blackhawks will be participating in 2017 IIHF World Championships?

The Blackhawks' season ended much sooner than expected after being swept in the first round of the Stanley Cup playoffs by the Nashville Predators. The IIHF World Championships begin May 5, and an early postseason exit gives several Blackhawks an opportunity to play in the tournament. With the National Hockey League saying it will not participate in the 2018 Winter Olympics, players may be more inclined to join given the uncertainty of when they'll be able to represent their countries again if ever, for some.
