For Dallas, this is a cap move to clear salary. Pittsburgh will take on his $3.75 million salary and in exchange, get a second-round draft choice. For the Penguins, Dumba is a gritty defenseman known for his edge and shot, bringing veteran leadership to Pittsburgh.

With a career spanning 2009–2025 across eight teams, Dumba’s recent decline in ice time suggests aren’t likely to get much out of the blueliner. However, they could be banking on him in a depth role as the Penguins try to stabilize their defense during a rebuild.

Conversely, Dallas acquires Kolyachonok, a 24-year-old with offensive potential but limited NHL experience (12 games with Pittsburgh). While Kolyachonok’s immediate impact is uncertain, his youth could add long-term value.

No further trade package details have been released.
