What happened: The Buffalo Sabres are sending defenseman Bowen Byram and forward Jordan Greenway to the Chicago Blackhawks. In return, Buffalo receives the No. 4 overall pick in the 2026 draft, defenseman Adam Crevier and a second-round selection. The move reshapes both rosters ahead of the draft.

Why it matters: Byram, a 25-year-old top-pairing defenseman, had been at the center of offseason trade speculation for weeks. Buffalo converts that interest into a high draft pick, leaning into a longer-term build, while Chicago adds an established defenseman and forward depth to accelerate its return to contention.

What to watch: Watch how Buffalo uses the No. 4 selection and whether the freed cap space funds further offseason moves. For Chicago, the focus shifts to integrating Byram into the top four.
