Mismash was a second-round pick in the 2017 draft and turned pro in 2022 after four years at the University of North Dakota. The 23-year-old winger had 12 points (6G / 6A) in 57 games with Milwaukee (AHL) and will likely report to Syracuse (AHL) next year.
Myers was traded to the Predators last year as a part of the Ryan Ellis and Nolan Patrick three-way trade. He appeared in 27 games with Nashville, posting one goal and three assists (four points). Myers should have a chance to crack the Lightning's blueline rotation to start 2023.
McDonagh has four years left on his seven-year deal that carries a $6.75M AAV cap-hit. The Lightning recently approached McDonagh to waive his no-trade clause in an effort to clear some cap-space. The Lightning have two key UFA's in Ondrej Palat and Jan Rutta and this trade could help get both of them under contract. In Nashville, McDonagh joins Roman Josi, and Mattias Ekholm as the Predators' new big-3.
Olivier was a key member of the Predators in 2021 but fell behind the eight-ball with an injury in 2022, spending most of the year in the AHL. The rugged winger has seven points (3G / 4A) and 102 hits in 48 career NHL games. He'll likely be a fringe roster player for the Blue Jackets in 2022-23.
Fiala was set to become an RFA and the Wild likely weren't going to have the cap-space to re-sign him. They moved him and added a second first-round pick in 2022 and Brock Faber, who was a second-round pick (No.45 overall) in 2020. For Fiala, he heads to Los Angeles, where he'll likely play a key top-6 role next to either Anze Kopitar or Phillip Danault. Fiala is coming off of the best season of his career, scoring 33 goals with 52 assists (85 points) in 82 games.
