Buffalo Sabres prospect Radim Mrtka, the ninth overall pick in the 2025 NHL Draft, continues to impress as the defenseman makes a strong case for a full-time jump to pro hockey next season.
Mrtka received a four-game stint with the AHL's Rochester Americans this season (and held his own) before returning to junior hockey with the WHL's Seattle Thunderbirds. He's recorded 34 points (one goal and 33 assists) in 43 appearances for the Thunderbirds in 2025-26.
ESPN's Rachel Kryshak ranked the 18-year-old blueliner as the Sabres' top prospect ahead of Amerks forward Konsta Helenius on Tuesday.
"The physical profile alone is rare, standing 6-foot-6, 216 pounds, and being a right-handed shot," Kryshak wrote. "But what makes Mrtka special is how well he moves around the ice with that frame. His first step is quick, his pivots are clean and he escapes pressure with poise."
She added: "Mrtka is going to fit perfectly on Buffalo's talented blue line."
Along with his strong performance in the WHL, the Czech defender also gained valuable experience by playing for his national team at the 2026 World Juniors. Czechia reached the tournament's championship game before falling short against Sweden.
Radim Mrtka popped up in rumors ahead of the 2026 NHL trade deadline but any deal would come with extreme risk for the Buffalo Sabres
Although it was never confirmed by either side, there was heavy speculation the Sabres were set to trade Mrtka and a first-round draft pick to the St. Louis Blues as part of a package for veteran defenseman Colton Parayko ahead of the deadline.
Parayko decided to use his no-trade clause to block a move to Western New York, and that may ultimately be a blessing in disguise for Buffalo.
As Kryshak alluded, players with Mrtka's combination of size, skating ability and offensive play-creation skills don't come around often. He's still a work in progress in his own zone, though he's made clear strides this season, and adding more muscle to his frame will be necessary before his NHL arrival.
His timeline also perfectly matches the Sabres' blue-line outlook. The top four of Rasmus Dahlin, Owen Power, Mattias Samuelsson and Bowen Byram are all under contract for next season, but Byram is scheduled to become an unrestricted free agent in 2027.
Buffalo's front office, led by general manager Jarmo Kekalainen, may decide to maintain the status quo for 2026-27 given the defense's success and importance to the team's remarkable turnaround, but it's unlikely the club will have the financial flexibility to keep Byram for the long haul.
On paper, that would give Mrtka a full season of AHL development in Rochester before potentially joining the Sabres roster in 2027-28.
It'll be intriguing to see whether the right-shot defenseman's name ends up back on the trade block this season. The Blue and Gold are clearly trying to turn a corner toward sustained Stanley Cup contention and Kekalainen may desire a proven commodity rather than a prospect with some development runway left.
Yet, Mrtka's maximum upside — a true first-pair defenseman with a two-way skill set — would add a lot of downside risk to any trade equation, especially he'll be on a team-friendly contract for several years compared to a player like Parayko ($6.5 million AAV through 2029-30).
That's an important distinction for an organization set to face some tough decisions over the summer with limited salary-cap space. Most notably, trying to keep Alex Tuch on a long-term extension will require some concessions in other areas.
So, while Kekalainen has a history of making bold moves dating back to his time as Columbus Blue Jackets GM and appears eager to continue reshaping the roster in his desired image, the Mrtka situation is one where exercising a little caution is warranted.
Trading away one of the NHL's most highly touted prospects could haunt Buffalo in the long run.
