What happened: Free agent center Mitchell Robinson has agreed to a three-year, $47.4 million contract with the Boston Celtics, with a player option in the third season. The deal moves Robinson to Boston after his run in New York, where he played a central role on the Knicks' championship team.

Why it matters: Robinson gives Boston a defensive-minded, rim-protecting center and lob threat to reshape its frontcourt for the 2026-27 season. For New York, losing the same Mitchell Robinson who was billed as a Finals X-factor removes an interior anchor from a title roster and reshapes the Knicks' offseason priorities up front.

What to watch: Watch how Boston fills out the rest of its frontcourt rotation around Robinson and how the Knicks respond at center after his departure.
