Marc-Andre Fleury is one of the nicest human beings in the history of the National Hockey League. He is also one of the greatest goalies in the history of the NHL as well. He is a three-time Stanley Cup Champion with the Pittsburgh Penguins and has had a tremendous amount of success with the Vegas Golden Knights as well. In 2020-21, he was so good that he won the Vezina Trophy and now he is on his way to the Chicago Blackhawks.
The Hawks sent a Minor League player named Mikael Hakkarainen to the Golden Knights to get Fleury back. If you are wondering why Vegas would do this, it is a fair question. They want to move on from Fleury so they can commit to Robin Lehner full-time and create more cap room for other areas. It is hard to win in the NHL with two goalies making that much money.
