Ullmark is coming off a remarkable season that saw him win the Vezina Trophy and post an absurd 1.89 GAA and .938 SV% in 49 appearances (40-6-1). Like last season, the talented Swedish goaltender should see a near-split in the crease with counterpart Jeremy Swayman but at least for the Bruins' season opener, the nod goes to Ullmark. The Bruins, who allowed the fewest goals in the league last season, are facing a Blackhawks team that travelled from Pittsburgh last night after defeating the Penguins 4-2. Despite the Blackhawks having rookie phenom Connor Bedard in the lineup, the Bruins are still massive -310 home favourites.

If MacEwen is unable to play in the season opener, the Senators will likely have to play with only 11 forwards. MacEwen recorded 10 points last season (4G / 6A) and 66 PIM across 56 games between the Philadelphia Flyers and Los Angeles Kings last season.

Thomson was placed on waivers by Ottawa and claimed by Anaheim on Sunday. The 23-year-old defenseman was Ottawa's 2019 first-round draft pick (19th overall) and had played 18 NHL games in two seasons for the Senators, picking up five assists. Thomson spent the majority of 2022-23 with the Belleville Senators (AHL) and had seven goals, 26 assists, 28 PIMs and a -9 plus/minus through 56 games.

Sanderson enjoyed a very successful rookie season in 2022-23 as he finished his inaugural campaign with four goals, 28 assists, 132 SOG, 12 PIMs, and a -6 plus/minus through 77 games played and has signed an eight-year, $64.4 million ($8,050,000 AAV) contract extension. The 21-year-old defenseman was Ottawa's 2020 1st round-pick (5th overall) and is expected to take a massive leap forward in his sophomore campaign.

Sebrango was a third-round pick in the 2020 NHL Entry Draft and split the 2023 season between Grand Rapids (AHL) and Toledo (ECHL). The 21-year-old was fairly deep on the Red Wings' defensive prospect depth chart, so it's not a huge loss for an organization that has invested a lot of draft capital in defensemen in recent years. During his time in the AHL, Sebrango had five goals and 13 assists (18 points) in 135 games over the last three seasons.

MacEwen had four goals, six assists, 64 PIMs, 73 SOG, and -11 plus/minus through 56 games with both Philadelphia and Los Angeles and has signed a three-year, 2.325 million contract with the Ottawa Senators.

Shepard was 20-8-5 with a .916 SV% and 2.18 GAA with the Hershey Bears (AHL) and has signed a two-year, two-way contract extension worth $775,000.

Zetterlund had six goals, 17 assists, 118 SOG, 14 PIMs and a -6 plus/minus through 67 games played with both New Jersey and San Jose and has signed a two-year contract extension worth $2.9 million ($1.45M AAV). The 23-year-old left-winger was acquired by San Jose at the trade deadline in the mega deal which saw Timo Meier head back to New Jersey.

Larsson spent most of 2023 in the AHL, where he had 17 points (4G / 13A) in 55 games with Belleville. During his time with Ottawa, he was held pointless with four shots and seven hits in seven games. It sounds like the Senators couldn't get Travis Hamonic re-signed, so they re-signed Larsson to maintain the blueline depth.

The Senators selected Pettersson in the third-round (No.72 overall) in the 2022 NHL Draft. The 19-year-old centre had one goal and one assist in 29 games with Rogle BK Angelholm (SHL) during the 2023 season.
