What happened: Columbus defenseman Zach Werenski used his no-trade protection to block a proposed deal that would have sent him to Dallas, according to a source. The trade was believed to involve a package moving back to Columbus, but Werenski declined to approve the destination. The two sides now appear back at square one on any potential move.

Why it matters: Werenski is the centerpiece of any Columbus reshaping this offseason, and his refusal narrows the market for a blue-liner the Blue Jackets have been fielding calls on. His veto power gives him effective control over where — and whether — he plays next, complicating Columbus' effort to extract a roster return. It also signals Dallas was not a fit despite the Stars' interest.

What to watch: Watch whether Columbus pivots to a destination Werenski will accept, with reporting pointing to Tampa Bay as his preferred landing spot. Any new framework will need his sign-off before it can close.
