Stillman appeared in 52 games with the Blackhawks in 2022, scoring two goals with 10 assists (12 points), while delivering 122 hits and blocking 67 shots. Stillman is likely insurance for Tyler Myers, who suffered a lower-body injury this week.

Lundkvist was selected No.28 overall in the 2018 NHL draft and registered four points (1G / 3A) in 25 NHL games with the Rangers last season. He spent most of the season in the AHL, posting 15 points (3G / 12A) in 34 games. Lundkvist will battle with Thomas Harley and Colin Miller for playing time in Dallas and could be a future D-partner of Miro Heiskanen.

Poehling was a first-round pick back in 2017 and has 13 goals and nine assists (22 points) in 85 career NHL games with Montreal. Poehling has spent some time in the NHL in each of the last three years but should be a bottom-6 option for the Penguins in 2022-23.

Matheson is coming off of a career-year, posting career-bests in goals (11), assists (20) and points (31) in 74 games with the Penguins. Matheson averaged 18:44 TOI/gm in two years with the Penguins butu could take on a larger role in Montreal, where there is not many experienced NHL defensemen.

Marino is a solid two-way, puck-moving defenseman that is an upgrade defensively from Smith. Marino should fill a top-4 role in New Jersey and will chip in a little offence, averaging 27 points (4G / 23A) per 82 games throughout his career.

Smith was a first-round pick in 2018 and had a nice rookie season (2G / 21A in 48 games) but struggled in his second season. The move to Pittsburgh provides the Penguins with a little salary relief for this season and a defenseman with some untapped offensive potential. Swapping Marino for Smith is certainly a downgrade defensively for Pittsburgh.
