For years, the conversation around the Buffalo Sabres has been about turning a corner. The young NHL core is in place, but the true path to becoming a perennial contender is paved by a deep, impactful prospect pool. As we head into the 2025-26 season, the system is brimming with a fascinating mix of high-octane skill, towering size, and pure hockey IQ that should have Sabres fans buzzing. This isn’t just about finding another roster player; it’s about identifying the next wave of difference-makers who will support the likes of Tage Thompson and Rasmus Dahlin.
The talent is diverse, from recent high draft picks adjusting to North America to prospects who are already getting a taste of NHL action. We’re breaking down the top five prospects who are shaping the future in Western New York, and my inside take is that one of them is already knocking on the door for a full-time job this season.
Breaking Down the Sabres’ Next Wave of Talent
At the top of the list are the recent first-rounders, Konsta Helenius and Radim Mrtka. Helenius, a versatile forward, silenced any doubts about his transition to North American ice with a stellar AHL playoff performance. The word from Rochester is that his hockey IQ is off the charts, a trait that always accelerates an NHL timeline. Mrtka, on the other hand, is the unicorn every GM dreams of: a 6-foot-6, right-shot defenseman with mobility and offensive upside. He’s a project, but his ceiling is a top-pairing anchor.
Then you have the trio of skilled forwards who bring different dimensions. Noah Ostlund is a sublime playmaker who just needs to add strength to his frame, while Anton Wahlberg offers a tantalizing combination of size (6-foot-5) and skill, showcased at the World Juniors. The organization wants to see him use that frame to create havoc around the net, the final piece of his development puzzle.
But the name that keeps coming up in front-office circles is Isak Rosen. After five separate call-ups last season and leading Rochester in scoring, the 22-year-old winger has proven he can produce at the professional level. His offensive instincts are elite, and of this entire group, he is the clear front-runner to not just challenge for a roster spot in training camp but to seize a full-time role with the Buffalo Sabres for the 2025-26 season.
