The Buffalo Sabres signed Olen Zellweger to a three-year, $9.3 million contract extension ($3.1 million AAV) through the 2028-29 NHL season on Wednesday. The 22-year-old defenseman had been set to become a restricted free agent.
Here's the best part for Buffalo: Zellweger will remain an RFA when the new deal expires in 2029, giving the Blue and Gold team control on a high-upside blueliner.
"He's just getting started," Sabres general manager Jarmo Kekalainen told reporters. "He's playing 17 minutes a game. We always say that defensemen need about 200 games before you can really see what they become. He's not there yet, so I think he's just growing as a defenseman right now."
Zellweger recorded 51 points (16 goals and 35 assists) in 164 appearances across three seasons with the Ducks, who selected him in the second round of the 2021 NHL Draft.
Buffalo acquired the 5-foot-10 defender from Anaheim last week in exchange for the No. 45 overall pick in the 2026 draft, which became defenseman Jayden Kurtz, and forward prospect Anton Wahlberg.
Zellweger is now one of seven NHL blueliners under contract with the Sabres for next season. He joins Rasmus Dahlin, Mattias Samuelsson, Owen Power, Conor Timmins, Louis Crevier and Zach Metsa.
Buffalo Sabres have a few options for Olen Zellweger's role in 2026-27
The initial thought when Buffalo brought in Zellweger from Anaheim was that he'd fill the spot vacated by Bowen Byram on the second pair alongside Power.
That's certainly a possibility. They play a similar offense-first style and bring a lot of transition value to the table, which is important since the Sabres lean heavily on their defense to help generate scoring chances, both at even strength and on the power play.
It's not the only path forward, though.
Buffalo could opt to slot in a right-shot blueliner, either Timmins or Crevier, next to Power, with the other one slotting in next to Zellweger on the third pair.
What's intriguing about that idea is it'd allow both Power, whose offensive production dipped this past season to 29 points in 81 games, and Zellweger to take on more puck-carrying responsibilities. It'd also bring more balance to the club's defensive bottom four.
The Sabres need to get more out of Power. He's taken positive strides since the franchise selected him with the first overall pick in the 2021 NHL Draft but he hasn't become a game-changing force. Giving him more attacking freedom could help that cause.
Although a Power-Zellweger pairing could surely work for Buffalo, it leaves the less palatable tandem of Timmins and Crevier, both right-shot players, for the third pair.
Finally, it's still possible the Sabres pull off a trade (or free-agent signing) for a little added defensive depth. It's one of the items on the team's to-do list along with a top-six scorer (preferably focusing on a top-line center) and maybe a veteran goalie.
If Kekalainen does make another addition to the blue line, it would likely make Timmins a trade candidate since Buffalo will want both Zellweger and Crevier in the lineup.
All told, a few more changes could be on the horizon after a busy start to the summer for the Blue and Gold, but there's no doubt they view Zellweger as a defensive building block.
His team-friendly contract merely adds to the upside of the trade they made with the Ducks to get the Canadian ahead of the draft.
