Moussa Cissé signs an offer sheet with the Knicks, Mavericks have two days to match

New York’s offseason has added another name to its frontcourt conversation, with restricted free-agent center Moussa Cissé reportedly signing an offer sheet with the Knicks, according to ESPN’s Shams Charania as relayed by Yahoo Sports. Under NBA restricted free-agent rules, that does not end Dallas’s involvement immediately. The Mavericks now have a limited period to match the offer and keep the player under their control.

The procedural significance is straightforward but consequential for roster planning. An offer sheet indicates a rival club has agreed to contract terms with a restricted free agent, but the original team is granted a chance to match that deal. If Dallas matches, Cissé stays with the Mavericks on the matched terms. If Dallas does not match within the window, the player can sign with New York.

Cissé’s fit is partly defined by what he did in Dallas last season. The report notes he played in 38 games and averaged 4.5 points and 5.7 rebounds per game. Those numbers place him in the category of a rotation big who contributes with volume rebounding and interior presence rather than serving as a primary scoring engine.

For the Knicks, the attraction of an offer sheet is that it can secure a ready-to-play center without forcing the team to give up unrestricted assets, at least not in the same way a trade would. For Dallas, the stakes are that matching would preserve depth and continuity in the middle. Choosing to match is typically about maintaining role players who fit a team’s defensive and rebounding structure, especially when the market for centers can be uneven from team to team.

The timing also matters. The report describes a two-day matching window for the Mavericks. That short runway can compress internal decision-making, from cap and roster construction considerations to how the front office values Cissé’s role compared to other priorities in free agency or follow-up moves.

It is also worth noting what the report does not clarify. The Yahoo Sports write-up frames the move as a reported offer sheet signing, not as an official league transaction confirmation. Until the NBA and the teams publish contract details through official channels, the exact terms, effective timing, and the Mavericks’ final decision remain subject to the matching outcome.

What to watch next is simple: whether Dallas matches the offer within the stated deadline, and if so, what that means for the Knicks’ remaining offseason opportunities at the center position. If Dallas declines, New York would gain a center it can integrate into its frontcourt rotation with the understanding that Cissé’s recent NBA production has been built around rebounds and efficient, low-usage contributions.
