Hagg signed a one-year, $775,000 contract with the Golden Knights on Tuesday, per PuckPedia.

Hagg played in just five NHL games with the Ducks last year, and he added 12 points in 47 contests for AHL San Diego. He's unlikely to see regular playing time with the Golden Knights, but he could fill in as a depth option when injuries arise.

Johnson signed a one-year, $775,000 contract with the Blue Jackets on Tuesday, per PuckPedia.

Johnson had a seven-year stint with the Blue Jackets earlier in his career, which accounted for most of his most successful seasons. At 37 years old, it's unlikely he returns to his former glory on offense. Instead, Johnson will likely serve as a veteran leader for the Blue Jackets' young roster, and he's expected to fill a third-pairing role.

Schmidt signed a one-year contract with the Panthers on Tuesday, Tim Reynolds of the Associated Press reports.

Per CapFriendly, his salary will be $800,000. Schmidt was bought out by the Jets ahead of free agency and will now link up with the defending champions. The 32-year-old defenseman has been little more than a third-pairing option in recent years, but he'll replenish the Panthers' blue line while reuniting with head coach Paul Maurice. Schmidt had 14 points, 76 blocked shots, 66 hits and a plus-10 rating over 63 regular-season appearances in 2023-24.

Myers signed a one-year, $775,000 contract with Toronto on Tuesday.

Myers generated four goals, 23 points and 67 PIM in 61 regular-season contests for AHL Syracuse in 2023-24. He didn't earn a point in five regular-season appearances with Tampa Bay this past campaign despite earning six shots on goal, eight hits and six blocked shots. Myers will probably spend most, if not all, of 2024-25 in the minors after getting a look at Toronto's training camp.

Mermis signed a one-year, $775,000 contract with Toronto on Tuesday, according to CapFriendly.

Mermis compiled three goals, eight points, 42 shots on net and 59 blocked shots in 47 regular-season appearances with Minnesota in 2023-24. As a member of the Maple Leafs, he will compete for a depth spot on the roster out of training camp.

Joseph signed a one-year, $950,000 contract with St. Louis on Tuesday, per Elliotte Friedman of Sportsnet.

Joseph compiled two goals, nine assists, 42 shots on net, 44 blocked shots and 47 hits across 52 regular-season contests with Pittsburgh in 2023-24. He will add some depth to the blue line of St. Louis. Ottawa traded forward Mathieu Joseph to the Blues on Tuesday, allowing Pierre-Olivier to be on the same team as his older brother.

Dumoulin was traded to the Ducks from the Kraken on Tuesday in a swap for a 2026 fourth-round selection.

Dumoulin apparently has found himself as the odd man out after the Kraken signed Brandon Montour to a seven-year deal Monday. After spending his first 10 seasons with the Penguins, the veteran blueliner will now be on this third team in as many seasons after spending just one year in Seattle. While Dumoulin has reached the 20-point threshold twice in his career, that is certainly not the norm for the blueliner, who is more likely to offer between 15-20 points per season.

Aho agreed to terms on a two-year, $1.55 million contract with Pittsburgh on Tuesday.

Aho managed just nine points in 58 regular-season games for the Islanders last season while averaging 16:23 of ice time. The 28-year-old Swede joins fellow free-agent acquisition Matt Grzelcyk on a revamped Penguins blue line, though a spot in the lineup is not guaranteed for Aho. He'll enter training camp in a positional battle with the likes of Jack St. Ivany and John Ludvig (wrist).

Poolman signed a one-year, two-way contract with Buffalo on Tuesday.

Poolman chipped in three goals and three assists across 66 regular-season outings with AHL Calgary in 2023-24. The 28-year-old defender doesn't have any NHL experience. Poolman will likely begin the 2024-25 campaign in the minors.

Brannstrom signed a one-year, $900,000 contract with Colorado on Tuesday, Elliotte Friedman of Sportsnet reports.

Brannstrom won't find minutes easy to come by with the Avs, especially after the team re-signed Jacob MacDonald and brought in Calvin de Haan. At best, Brannstrom figures to be the sixth or seventh blueliner heading into the 2024-25 campaign.
